WebSocket connection works in local machine but not in server - php

I am using the Laravel Framework and BrainSocket to open up a websocket service in a port via the following command line:
php artisan brainsocket:start --port=7778
Afterwards, I connect to the websocket on the client-side, like so:
var websocket = new WebSocket('ws://127.0.0.1:7778/');
At first I was developing this application on my local machine and everything was working fine. However, on the production server (CentOS 7 + Nginx), when I run the above line the following error message appears:
WebSocket connection to 'ws://127.0.0.1:7778/' failed: Connection
closed before receiving a handshake response
I tried changing the IP for the server's IP address, I have already checked if the port was being used and I made sure socket support was enabled. But whatever I do the same error message appears.

It worked once I used port 443 instead.

Fatal error: Uncaught mysqli_sql_exception: No connection could be made because the target machine actively refused [duplicate]

I'm using the WCF4.0 template -REST. I'm trying to make a method that uploads a file using a stream.
The problem always occur at
Stream serverStream = request.GetRequestStream();
Class for streaming:
namespace LogicClass
{
public class StreamClass : IStreamClass
{
public bool UploadFile(string filename, Stream fileStream)
{
try
{
FileStream fileToupload = new FileStream(filename, FileMode.Create);
byte[] bytearray = new byte[10000];
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileStream.Read(bytearray, 0, bytearray.Length);
totalBytesRead += bytesRead;
} while (bytesRead > 0);
fileToupload.Write(bytearray, 0, bytearray.Length);
fileToupload.Close();
fileToupload.Dispose();
}
catch (Exception ex) { throw new Exception(ex.Message); }
return true;
}
}
}
REST project:
[WebInvoke(UriTemplate = "AddStream/{filename}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)]
public bool AddStream(string filename, System.IO.Stream fileStream)
{
LogicClass.FileComponent rest = new LogicClass.FileComponent();
return rest.AddStream(filename, fileStream);
}
Windows Form project: for testing
private void button24_Click(object sender, EventArgs e)
{
byte[] fileStream;
using (FileStream fs = new FileStream("E:\\stream.txt", FileMode.Open, FileAccess.Read, FileShare.Read))
{
fileStream = new byte[fs.Length];
fs.Read(fileStream, 0, (int)fs.Length);
fs.Close();
fs.Dispose();
}
string baseAddress = "http://localhost:3446/File/AddStream/stream.txt";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress);
request.Method = "POST";
request.ContentType = "text/plain";
Stream serverStream = request.GetRequestStream();
serverStream.Write(fileStream, 0, fileStream.Length);
serverStream.Close();
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
StreamReader reader = new StreamReader(response.GetResponseStream());
}
}
I've turned off the firewall and my Internet connection, but the error still exists. Is there a better way of testing the uploading method?

"Actively refused it" means that the host sent a reset instead of an ack when you tried to connect. It is therefore not a problem in your code. Either there is a firewall blocking the connection or the process that is hosting the service is not listening on that port. This may be because it is not running at all or because it is listening on a different port.
Once you start the process hosting your service, try netstat -anb (requires admin privileges) to verify that it is running and listening on the expected port.
update: On Linux you may need to do netstat -anp instead.
You don't have to restart the PC. Restart IIS instead.
Run -> 'cmd'(as admin) and type "iisreset"
You must set up your system proxy
You have to go through this path
controlpanel>>internet option>>connnection>>LAN settings>>
proxy
no tik:use proxy server
I got a similar error message like TCP error code 10061: No connection could be made because the target machine actively refused it in my current project. I find this 10061 error code cannot distinguish the case that the service endpoint is not started and the case that it is blocked by the firewall. Often, the firewall can be switched off, but the problem is still there.
You can test your code in the below two ways.
Insert code to get time A that service is started and time B that client sends the request to the server. If B is earlier than A, it can cause this problem.
Change your server port to another port that is also available in the system. You will find the same error code reported.
Above is my fix. It works on my machine. I hope it helps!
Check if any other program is using that port.
If an instance of the same program is still active, kill that process.
I had a similar issue. In my case the service would work fine on the developer machine but fail when on a QA machine. It turned out that on the QA machine the application wasn't being run as an administrator and didn't have permission to register the endpoint:
HTTP could not register URL http://+:12345/Foo.svc/]. Your process does
not have access rights to this namespace (see
http://go.microsoft.com/fwlink/?LinkId=70353 for details).
Refer here for how to get it working without being an admin user: https://stackoverflow.com/a/885765/38258
If you use WCF storm, can you even log-in to the WCF service endpoint? If not, and you are hosting it in a Windows service, you probably forgot to register that namespace. It's not very well advertised that this step is required, and it is actually annoying to do.
I use this tool to do this; it automates all those cumbersome steps.
Check whether the port number in file Web.config of your webpage is the same as the one that is hosted on IIS.
I had the same problem on my web server "No connection could be made because the target machine actively refused it 161.x.x.235:5672". I asked the Admin to open the port 5672 on the web server, then it worked fine.
I had a similar problem
rejecting localhost and 127.0.0.1.
cmd(admin) netstat -anb found the port running on 169.254.80.80 (dont know were that ip came from because my network ip was 10.0.0.5.
after putting in this IP it worked.
This Gives correct IP:
IPAddress ipAddress = ipHostInfo.AddressList[0];
Console.WriteLine(ipAddress.ToString());
I also faced problem in .Net Remoting Service in C#.
I got it solved in 3 steps:
Change Port of Protocol in all the files whereever it is being used.
Run your Host Server Program and make it active.
Now run your client program.
I could not restart IIexpress. This is the solution that worked for me
Cleaned the build
Rebuild
With this error I was able to trace it, thanks to #Yaur, you need to basically check the service (WCF) if it's running and also check the outbound and inbound TCP properties on your advance firewall settings.
With similar pattern, my rest client is calling the service API, the service called successfully when debugging, but not working on the published code. Error was: Unable to connect to the remote server.
Inner Exception: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it serviceIP:443 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception)
Resolution: Set the proxy in Web config.
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy proxyaddress="http://proxy_ip:portno/" usesystemdefault="True"/>
</defaultProxy>

I had a similar issue. In my case VPN proxy app such as Psiphon ، changed the proxy setup in windows so follow this :
in Windows 10, search change proxy settings and turn of use proxy server in the manual proxy
Make Sure all services used by your application are on, which are using host and port to utilize them . For e.g, as in my case, This error can come, If your application is utilizing a Redis server and it is not being able to connect to it on given port and host, thus producing this error .
For my case, I had an Angular SLA project template with ASP.NET Core.
I was trying to run the IIS Express from the Visual Studio WebUI solution, triggering the "Actively refused it" error.
The problem, in this case, wasn't connected with the Firewall blocking the connection.
It turned out that I had to run the Angular server independently of the Kestrel run because the Server was expecting the UI to run on a specific port but wasn't actually.
For more information, check the official Microsoft documentation.
I had similar problem. In launchSettings, my IIS Express was configured on one port, and there was another launch profile that started on another ApplicationUrl with another port.
Starting the web app up with the IIS Express profile led me to have the error.
I am using the Apache ActiveMQ Artemis AMQP message broker. I started getting the "No connection could be made because the target machine actively refused it" exception when trying to send and receive messages with the broker after a reboot. On a computer where the same type of broker still worked, netstat -anb showed that the broker was listening on the expected port 5672. On the computer with the error, the broker was not listening. On the computer with the error, starting the broker resulted in the following warning's appearing in Microsoft Event Viewer's "Windows Logs > System":
The system failed to register host (A or AAAA) resource records for network adapter
with settings:
Adapter Name : {286EE2DA-3D81-41AE-VE5G-5D761FD3925E}
Host Name : mypc
Primary Domain Suffix : myco.com
DNS server list :
55.77.168.1, 74.86.130.1
Sent update to server : 186.952.335.157:45
IP Address(es) :

Either the DNS server does not support the DNS dynamic update protocol or the authoritative zone for the specified DNS domain name does not accept dynamic updates.
To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.
I was able to use the broker without error after I ran the following in a cmd.exe with administrative privileges, rebooted, and waited about fifteen minutes:
ipconfig /flushdns
ipconfig /renew
ipconfig /registerdns

Can't connect to remote firebird server using ibase_connect() [duplicate]

I'm trying to connect to a remote Firebird database "test" (alias already added). It is not an embedded server, and is installed on VM with IP 192.168.1.147.
Here is my connection string:
User=sysdba;Password=masterkey;Database=test;DataSource=192.168.1.147
However I got an error:
FirebirdSql.Data.FirebirdClient.FbException (0x80004005): Unable to complete network request to host "192.168.1.147". ---> Unable to complete network request to host "192.168.1.147".
I've done some research on that but haven't got a clue yet. Some help needed. Thanks
My IP address is 192.168.2.108, and I can ping that server IP successfully
Make sure that
Firebird is running
Firebird is listening on port 3050 on the specified IP (or on 0.0.0.0)
Your firewall allows access to port 3050
You're using the correct host name
For Linux, the Firebird port is closed by default. You need to modify RemoteBindAddress in /etc/firebird/2.5/firebird.conf from
RemoteBindAddress = localhost
to
RemoteBindAddress =
and restart service.
Make sure you have excluded tcp port 3050 in VMs' firewall.
Ok. I think your connection to firebird is faililing because the firebird client looks up the network service file by name and does not find gds_db in the services file.
If your connection string refers to the host by using IP, the Client might fail to identify it because it gethostbyname() and not by IP
Manually include this in the file and you should be fine.
C:\windows\system32\drivers\etc\services

RabbitMQ consumers Connection refused on managed server. Possible reasons?

We are using Symfony 2.2 with the OldSound RabbitMqBundle. A rabbitmq server is running on another instance. The server configuration is fine as everything is working on localhost and messages are sent and retrieved from/by the server.
On our managed server we get following error by starting a rabbitmq:consumer. This must result from any missing permissions, closed ports or some other circumstances, which are different on the managed server (hetzner) than on the localhost.
Do you have any idea how to analyse or fix this problem?
Executed Command:
:~/../app$ php console rabbitmq:consumer -m 100 transfer_data
Error message:
[PhpAmqpLib\Exception\AMQPRuntimeException]

class.phpmailer.php SMTP -> ERROR: Failed to connect to server

I've been using class.phpmailer.php for some time but recently it stop working on my web server.
It is still working on my home computer but I guess that it's because I didn't update xampp.
The error returned is:
php SMTP -> ERROR: Failed to connect to server: A connection attempt
failed because the connected party did not properly respond after a
period of time, or established connection failed because connected
host has failed to respond. (10060)
I've also used this class eukhost and it sends the email with no errors.
I'm now going debugging class.phpmailer.php to see what is wrong.
But before I start, I would like to know if someone got this problem ans solved it.
If this had been working and now has recently stopped, it could be a temporary issue, or some settings for the mail server have been changed and you now need to update your settings.
The error message is telling you that it could not connect to the mail server. Socket error 10060 is a general operation timed out message.
You need to verify that the SMTP host and port numbers being used by phpmailer are correct. You should from another machine (or the same system running PHP) be able to telnet your-mail-server-here.com 25 where 25 represents the port number.
If you can't connect to the server, then the mail server is down or the hostname or port have changed. If you can connect from other systems but not from your PHP server, it is possible your IP has been blocked from the mail server, or a local/remote firewall are preventing your connection.
Hope that helps.

IIS + PHP + MySQL: A connection attempt failed because the connected party did not (trying to connect via tcp://localhost:3306)

I'm running Windows, having installed IIS 7.5, PHP 5.3 (FastCGI). Trying to connect to MySQL and getting an error "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.".
Started to develop a project with XAMPP, but had the requirement to move it to IIS (because of AD auth). MySQL is running from XAMPP stack. I've mapped IIS to the same docroot as Apache2's, but to another port. When accessing test page server with Apache2 host - there is no problem, but when accessing IIS + PHP FCGI page - I get this error.
will the standalone installation of MySQL help?
what are your advises?
In your script, try using "127.0.0.1" instead of "localhost" as MySQL host.
If this solves your problem you can add the following line to your hosts file in /Windows/System32/drivers/etc/hosts:
127.0.0.1 localhost
After that you will able to use "localhost".
try using "127.0.0.1" instead of "localhost" as MySQL host.
Just saved my life XD XD XD
