I upgraded to the new version and the fault was resolved
New installation without port 4567 in URL?
I've just made my test installation on nikica.net:4567
Do we need to use 4567 port or this can be changed.
We use Cent OS 6.7 and Apache Webserver.
You will need to setup Apache to proxy requests instead of forwarding them.
Everything you need should be here.
Since you are on CentOS 6, you are probably on Apache 2.2, and will need to follow these instructions first.
I would advise using Nginx infront of it.
You can google
NodeBB Nginx Configand you'll have one you can copy/paste.
Nginx will then be on port 80 and you can close 4567 on your FW.
