Supervisor access lost from dashboard

Hi all, I am having some trouble with my HomeAssistant installation. When I reboot my system the AddOn page and other Supervisor pages are shown normally. If I however check the next day this page shows me the Supervisor panel could not be loaded error. Rebooting ofcourse solves this issue, but is not something I should be doing every single day.
I already did an installation to HassOS (and import from backup) as I already had some notifications on my unsupported configuration but to no succes.
If I try to retrieve the logs from Supervisor via the Dashboard I am getting a 502 error

What could be wrong in my install?

It looks similar to Parts of HA get unresponisve after a few hours. Supervisor not reachable so trying that for now
