Hello :)

Check the following log file after logging in to see if you notice any specific entries at the time of the last failure:

Code:
/var/log/secure
Also, do you have any third-party firewall rules enabled that could be blocking the connection? Does the issue persist when you disable any such firewall rules?

Thank you.

There is a "Quick Allow" option in the CSF user-interface available in Web Host Manager that you can use to white list your IP address.

Thank you.

You may want to post directly to the ConfigServer forums for assistance with CSF if you feel it's a separate option in the CSF configuraton that is terminating the connection.

Thank you.

If CSF/LFD is blocking your IP you should see in in
/var/log/lfd.log
