Chat Application with port 8065 - IP not working

I have been struggling for couple of days that my chat application works only for 24 hours and then stops working. Then I realized that when I do login on CWP with root, my IP gets added in temporary list and chat app starts working. But users on other locations are still not able to connect.


Running Mattermost ( A clone of slack ) for a small team. It runs on port 8065. I have enabled this port in both TCP/UDP in/out sections.

I want it to accessible permanent from anywhere from any IP. Sometimes we do have to work from home and everyone can not have static IP.

Thank you

Did you even check your logs (/var/log/messages).. ??
Your server is OpenVZ .. ??
