@Ju_St If the server command works, but the systemctl service doesn’t, my best guess is that you’re hitting a permissions issue.

The storage location is set to the default ./data/ which is also where our files are saved when looking through the folders. Not a lot of new revelations I’m afraid…any suggestions on ho…

Hello ElNovi, thanks for your suggestion. “Forward 80 to 443” is already set to false in the mattermost config. We’ve set up all https related settings in our nginx config.

@ccbrown thanks, that did the trick! It seems I messed up setting the right permissions during the upgrade. I though I had changed the username and instead of checking just went for it. Feeling a bit stupid right now :smirk: In any case, thanks a lot for your help and patience! We’re on 4.6.1 now a…
