I’ve got a user sending me mails because he can’t post in the forum.
He said that the forum says “an error occurs” and can’t post messages, or new threads
This is connected with this error log?
My guess is you have something configured incorrectly in your network stack for your Discourse instance? Are either of you doing any weird proxying, or anything deviating from the normal Discourse Docker setup?
It’s probably a client proxy adding Client-IP:, then nginx adds X-Forwarded-For, and rails takes a look and says “okay none of these agree, so I don’t know what to trust, so I may as well throw an error”.
Not sure that that means. It’s a standard hosted install using the Discourse install guide. Single server, single install. No proxying, just a standard NAT firewall with a HTTP/S port forwarding to the discourse VM.
Am wondering could be due to a proxy at the client end?
