Site only opens in localhost - php

Question

I'm setting up a windows server 2019 with apache 2.4 and PHP 5.6.
I was able to load the phpinfo in the browser with localhost.
I am trying to get the sites to open up in an htdocs folder on another drive (D:) using an alias that, according to our networking team is quoting, "DNS is set up correctly pointing to newprod.company.name.com", with "newprod" being the acutal alias.
In my httpd.conf file, I have the following settings:
Define SRVROOT "c:/Apache24"
ServerRoot "${SRVROOT}"
Listen 80
The above is pointing at the C: drive where Apache24 is located.
LoadModule rewrite_module modules/mod_rewrite.so
I have the above module uncommented. There are several other modules that have been uncommented, but the one above seems to be one of the main modules that, according to various Apache setup tutorials, is the main module.
ServerAdmin my.company#company.com
ServerName newprod.company.name.com:80
ServerName Localhost:80
According to various tutorials, the above seems to be accurate. I have compared my previous httpd.conf files, and they work using very similar configurations, including Localhost:80.
DocumentRoot "D:/htdocs"
<Directory "D:/htdocs">
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
The main part to focus on above the D:/htdocs. This is where I figured the sites should be opening from, as well as opening using the alias.
<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>
The above is typical for an Apache setup, per various tutorials.
<VirtualHost newprod.company.name.com:80>
ServerName newprod.company.name.com
Redirect / http://newprod.company.name.com/
</VirtualHost>
I use the above on another server (with a different alias) without any issues.
PHPIniDir "C:/PHP5.6"
AddHandler application/x-httpd-php .php
LoadModule php5_module "C:/PHP5.6/php5apache2_4.dll"
Then finally, the above is to ensure Apache will read PHP.
I have two other servers that are loading the sites with their own aliases with no problem. I literally went line for line trying to ensure everything matches. The only things that don't match is the PHP configurations at the bottom of the file. My other two servers are using PHP 7.4, while the problem server is using PHP 5.6.
Why aren't my sites loading using the alias I provided?

Answer 1

If you're using
ServerName newprod.company.name.com:80
ServerName Localhost:80
in main httpd.conf (or main apache config file), get rid of
ServerName Localhost:80
The vhost configuration
<VirtualHost newprod.company.name.com:80>
ServerName newprod.company.name.com
Redirect / http://newprod.company.name.com/
</VirtualHost>
is probably going to create a redirect loop: if that's all the configuration inside the virtualhost, get rid of it: it's useless.
Is port 80 on your apache server reachable from another pc? Are you able to telnet from a pc in the same lan on po 80 of apache server? Have you checked if the firewall is dropping the first syn packet?
