@pitaj it is not just me, beeing happy !!! my whole community loves it. Thanks to you .. which made me reading all the docs again and found this miss configuration

@pitaj yes i have read this...

i finally resolved this issue..

it was the way nodebb got started in my initd script

the PIDFile was responsible for this bug

after correcting the path from

/var/run/nodebb.pid

to

/var/www/nodebb/pidfile

it works like a charm.. strange isn't it? but i am happy to finally got this resolved

thanks

@pitaj maybe in your archive.. i am not sure.. meanwhile i found the correct page.. but i am still not able to fix this problem

XHR polling is not working and WSS also not

Im running NodeBB 1.17.1 and nginx/1.19.6 on the same machine as proxy. The whole machine is behind cloudflare.

everything works beside a little problem with the socket.io

https://url.mydomain/socket.io/?EIO=4&transport=polling&t=NnHgkjh

gives very often 502 errors. Whatever i set in my nginx conf does not seem to help.

People loosing the connection for some seconds before they can continue.

is this a common problem or does it have something todo with cloudflare?

btw the page https://docs.nodebb.org/installing/os/configuring/nginx rerturn error 404 and is referenced in the documentation
