I have a domain was registered at godaddy named http://mysite.com/. I logged into godaddy and I went to All Products > Domains > Domain Management. I clicked on the appropriate domain and it took me to the Domain Details page. I clicked Launch under DNS Manager and it took me to the Zone File Editor. I noticed that notify.mysite.com was pointing to an IP address pointing to a dead server, so I switched it to an operating server. Then I pinged the domain to see where it was pointing to and it was correctly pointing to the working server. So I copied the default configuration under sites-available: sudo cp default notify.mysite.com. And then I made some edits to it to have it point to a different document root to serve files at a different port:

Listen 1740
Listen 64.135.xx.xxx:1740 #I also tried this as well: NameVirtualHost 64.135.xx.xxx:1740

<VirtualHost 64.135.xx.xxx:1740>

        ServerAdmin [email protected]
        ServerName notify.mysite.com

        DocumentRoot /var/www/test/public

        <Directory /var/www/test/public>
           Order allow,deny
           allow from all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn

        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Then I enabled the virtual host. Then I went to the document root and added an index.html file with some text in it. Then I restarted apache. The restart gave no errors.

Then I type the correct domain in URL:

http://notify.mysite.com:1740/

and I get:

Oops! Google Chrome could not connect to notify.mysite.com:1740

Somehow it took out all my other sites. Now even the ones that were responding on port 80 are no longe responding, even though I did not touch the virtual hosts for them.

I get this message now:

Oops! Google Chrome could not connect to mysite.com

However, ping responds:

The result of telnet:
