Yeah @kurulumu-Net you can change port in config.json in one of the NodeBBs and change to the same port in the proxy-pass part of the corresponding nginx config.
Default port is 4567, one will need to be changed.
Nginx has many possibilities for optimizing nodebb. In this post, I invite you to share the most interesting practices for optimizing our community.
For an automatic transition from www to no www, this code works well
if ( $host ~ ^www.(?<domain>.+) ) {
rewrite ^/(.*)$ $scheme://$domain/$1;
Express.js does not support http/2. Or am I wrong? Does it make sense to include http/2 support in nginx?
