      Sometimes you need to restart your Cloudron instance.
      This situation happens after the last reboot.
      Mongodb in a loop.
      Does anyone have a genius idea?

        That is indeed strange and quite the huge workaround. Did you try to empty that mongodb folder, then restart the mongodb addon and then restore the apps? This should also recreate the mongodb with an empty database.

          Wow. What a ride.
          Something was deeply broken.

          My solution was:

          • ssh into Cloudron
          • rm -rf /home/yellowtent/platformdata/mongodb
          • Install a fresh Cloudron on a different vps
          • rsync the mongodb folder from the newly installed Cloudron to the broken instance
          • restore app backups (in my case rocket.chat & wekan)

              @nebulon nope. next time I will try it this way 🙂
              I deleted some of the files in the mongodb folder, which looked like the database, configuration and index of the applications. But afterwards it was the same behaviour (restarting the mongodb app itself). With a completely empty mongodb folder I never tried it.

                @nebulon I was having a similar issue with Mongodb since a few days, I backuped the mongodb folder, created a new one, restarted the mongodb service, restarted the apps and the problem is solved 🙂
