Ok, i think nobody will answer that question. After dig it i realised that the issue is about apache mod_proxy_wstunnel. When nodebb works on TCP port there is no problem but on unix socket it seems that mod_proxy_wstunnel is not meant to work with Unix domain sockets. For example; ProxyPass "/ws" "unix:/tmp/nodebb.sock|ws://127.0.0.1/" not work. Best Regards,

Yes, you are right, thank you. My redis.conf file was broken. As usual, at the end of the day redis error finds you ! Finally setup is done. My nodebb setup experience = Hey nodebb ! if you want to grow you have to support MySQL. It isn't important how fast redis is because it does not give confidence any time. Best Regards,
