19 hours ago Do you have logs from server?
You can try increasing the timeout inside your apache config for proxy:
ProxyTimeout 300
ProxyConnectTimeout 300
ProxySendTimeout 300
ProxyReceiveTimeout 300As a second debug step, you can try disabling buffering to ensure real-time updates flow correctly without delay:
SetEnv proxy-nokeepalive 1
Summary
Since upgrading my Mattermost instance to 10.0.1 (bundled with Gitlab), the connection through a reverse proxy is unstable https://docs.mattermost.com/configure/config-proxy-apache2.html with the browser and the android app (least).
Steps to reproduce
Setup mattermost behind a reverse proxy as outlined in https://docs.mattermost.com/configure/config-proxy-apache2.html Connect with the app or from a browser through the reverse proxy. You would get the message "The server is not reachable" and sending messages will go to the retry mechanismn, but sometimes they go through. Incoming messages also do not arrive.
Operating System
Android App 2.21.0
Mattermost Server Version
Gitlab Mattermost Version 10.0.1
Expected behavior
Stable communication with the server, outgoing messages leaving without retry.
Observed behavior
You get the message "The server is not reachable" and sending messages will go to the retry mechanismn, but sometimes they go through. Incoming messages also do not arrive.
Log Output
Not sure how to get logs from Android.
Additional Information
I am aware that the functionality behind a reverse proxy is labeled as unofficial and you probably don't support Gitlab Mattermost, but I would be surprised if the Gitlab team touches this part of the code and wanted to report the issue nonetheless in case the linked reverse proxy guide needs an update for 10.x.
