    @nebulon yes it works now ! Great ! That it means this problem can occur on a new app install ? And what about a restart or restore of an openproject app ? Thanks

      So the was indeed a bug in the platform code with the port change. This is now fixed and will be part of the next Cloudron release.

        Based on my diagnosis, this is caused by the "worker" scheduler/cron task. Every time that runs (based on the log), I see a new file in /app/code/tmp/cache owned by root. Sometimes this new file is in a new directory (as the cache splits the storage across multiple directories on demand based on the random file name). When this newly created root owned folder is used by the normal process (running as www-data), it fails the permission check and users see the error message.

        I've been "fixing" this by manually running

        /app/code/tmp/cache# find -user root -exec chown www-data:www-data {} \;
        

        at the terminal.

          @peter-newman ah great observation, I will release a new package with a fix then. I guess I can revert the apache and thus port change patch then.

            hi @nebulon, i don't know if it is due to your update but we encounter the not responding screen on openproject on an up to date and restarted server. I sent you an email.

              @benoit this is likely the same issue as after the other update, just recreate the nginx configs via submitting the domain/location settings without changing them in the app configure screen. This will be fixed with Cloudron 6.1

                  Oh I see. Since I had access to your instance for fixing the issue anyways, I saw that the app was healthy and running, but the nginx reverse proxy config wasn't correctly updated.
                  This may actually be a bug in Cloudron. The reason likely is that I've changed the app's internal port from 80 to 8000 to not require apache to run as root.

                  To fix this quickly, I've just submitted the location form of the app configure, which triggers a recreation of the reverse proxy files.

                  At least for me the app is now reachable.

                  This explains a lot.
