i don’t know how to troubleshoot my problem with my nextcloud box. since a couple of days it just stopped working - i’m unable to access it through browser, caldav sync (thunderbird) or nextcloud sync client (linux desktop and mobile). davdroid on android says “500 internal server error”. however, i can still ssh into the box, and have updated repositories and upgraded the available packages.
i started a thread, hopefully in the right subsection?
