OK, that wasn't the issue. We have an issue with the Cloudron 5.6.1 release that http://ip will serve up a random app. This is because we ended up removing 'default_server' and the nginx behavior is to serve up the first server it finds. Not the end of the world, but not nice. This issue has been fixed now.
I thought the above was the reason you were getting served up some other app when you put an app in repair mode. I tested it now, but this is not the case. If you can duplicate this and let me know, I would like to have a look.
