A connection attempt failed error - php

Hi everyone I'm trying to set up a MySQL connection to a web server on Dreamweaver but keep getting the 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.
How can I resolve this?
The connection seems to be working fine when I test it on the actual web server but it does not work when I run it off the local web server (off 127.0.0.1). What could be the problem?

can you connect to it from the command line?? mysql -u your_user -p -h thehost if you're connecting remotely your mysql user should have a specific GRANT that specifies the ip you are connecting from

mysqli_connect(): (HY000/2002): A connection attempt failed to the remote server

I am trying to connect to a remote mysql server, but I get the
Warning: mysqli_connect(): (HY000/2002): 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.
This connection worked until a few days back, but I suspect an antivirus update changed the permissions for the port. I am unable to figure it out and it's already frustrating.
I am using XAMPP, which I already reinstalled. I have also tried in WAMP, so it is not local webserver related.
Telnet fails when opening connection to host, my IP is allowed on the remote server.
I have also disabled the antivirus and firewall temporarily, but still fail to connect. What else should I try?
First check no other application is using the port. Because of the problem MySQL can't start at the port . check it and is not work means reinstall the xampp with another place like D: , E: , something else.

Remote mySQL, can connect from remote SSH, but remote php/httpd fails to connect

I have a new drupal site running behind a load balancer. I've got one master slave set up with the database and another that syncs files from the web dir.
For the remote slave, I've got ENV vars setup for the database host, which is the INTERNAL IP of the master slave holding the database. This works fine as the master has this too with it's ENV var being 'localhost'
Now, when accessing the site, getting put on the master slave works fine. But when hitting the remote slave I get the database error from Drupal :
PDOException: SQLSTATE[HY000] [2002] Can't connect to local MySQL
server through socket '/var/lib/mysql/mysql.sock' (2) in
lock_may_be_available() (line 167 of /var/www/html/includes/lock.inc).
I've run the regular GRANT commands for the remote slave and I can connect over SSH from the slave machine using
mysql -u root -p -h master.slave.internal.ip
So from what I can tell it's not a firewall or mysql permissions issue, I'm stumped! :(
Big beer coming someones way, as I'm left scratching my head.
It looks like your Drupal config is wrong if you need to connect to a database on a different server. The error message says it can't connect to the "local MySQL server", not that it can't connect to "MySQL on server ". Look at settings.php and make sure the database ip address/hostname is correct.

Remote MySQL Connection in PHP

I'm beginning to migrate a software project from being a desktop application to a web application. Currently I am using a local PHP/MySQL connection that is associated with the desktop it is installed on.
I'm hoping to untangle this and am trying to create a MySQL database through my 1and1 account. I had no trouble creating a database and recorded my account information. I'd like to be able to edit this database using PHP scripts on my system. However, I haven't been able to get a working connection string going. When I run the following PHP script:
$hostname="db*********.db.1and1.com";
$database="db*********";
$username="dbo*********";
$password="*********";
$link = mysql_connect($hostname, $username, $password);
I get the following error when I run the script in my webbrowser:
Warning: mysql_connect() [function.mysql-connect]: Unknown MySQL server host 'db*********.db.1and1.com' (11001) in C:\Program Files\xampp\htdocs\Remote_MySQL\rightbid_database_initialize.php on line 74
Connection failed: Unknown MySQL server host 'db*********.db.1and1.com' (11001)
How do I get my local system to recognize the 1and1 server host? Am I structuring my connection string correctly? Is it possible to access a remote server from a locally hosted Windows PHP connection?
Thanks!
I assume what's happening if that 1&1 are blocking any connections coming from outside of their network.
Try connecting using
mysql -h HOST -u USERNAME -p DATABASENAME
Good luck
Make sure the MySQL server on 1and1 will accept connections from remote clients. Not just on localhost, and also make sure port 3306 is open to the server.

My SQL Error: A connection attempt failed because the connected party did not properly respond

I have a MySQL database in a 3rd party server. I am trying to access it from my local machine using PHP in Dreamweaver. However, I am getting the following error:
MySQL Error #2002:
A connection attempt failed because the connected party did not properly respond
after a period of time, or established connection failed because connected host
failed to respond.
Thank you.
It means you can't connect to the server. Check your connecting to the correct IP address and your firewall is configured to allow traffic.
If your using "localhost" also try host name as 127.0.0.1. If its server try from mysql terminal whether that host is connecting from your local machine.
In local machine I have faced same issue with host localhost and changed to 127.0.0.1 then its works well.

Why am I getting mysql_connect(): Lost connection to MySQL server and how can I fix it?

My php code fails to connect to the mysql database on my web server. I get the following error:
mysql_connect(): Lost connection to MySQL server at 'reading initial
communication packet', system error: 110 in filename at line 71.
The same code works fine when run from my development machine pointed at the mysql database on the server I'm trying to run this from (I copied the file up to the server and I'm trying to run it via ssh on that server). I have verified that the mysql user in the script can connect to the database from the server by running mysql from the ssh command line on that server using the same user name and password as specified in my php script.
here is my code:
function jsw_set_cnxn($env){
global $env;
$cnxn = mysql_connect($env['db_svr'], $env['db_usr'], $env['db_pwd'])
or die ('DB Connection Error: ' . mysql_error());
mysql_select_db ($env['db'], $cnxn);
return $cnxn;
}
I've seen this error caused when using the servers IP address when it expects localhost as the server address.
This is because the server is the machine mysql expects but the wrong host coming in. Try using localhost.
