Supervisor Panel Not loading

My Long running Home assistant install (running on rpi using docker, previously installed using script here: https://github.com/home-assistant/supervised-installer ) has suddenly failed to load the supervisor panel.

All addons appeared to still be running but the supervisor panel just produced the following:

Looking at the logs shows the following:

21-10-22 20:32:15 ERROR (MainThread) [supervisor.api.middleware.security] Invalid token for access /homeassistant/options
21-10-22 20:32:15 ERROR (MainThread) [supervisor.api.middleware.security] Invalid token for access /supervisor/options

21-10-22 20:32:15 ERROR (MainThread) [supervisor.api.middleware.security] Invalid token for access /ingress/panels

I have searched the forums far and wide and while the issue is reported multiple times over the years, there seems to be no single source issue. In desperation I followed the following comment: https://github.com/home-assistant/supervisor/issues/1576#issuecomment-610156611 and stopped services using systemctl, killed the remaining containers and reran the installation using the script, which finished with no error, restarted the supervisor, which in turn started the other core HA docker containers. HA is running once again with the same issue.

At this point I tried using the ha cli to restore a backup of core_2021.10.1 (same issue) and went even further back to core_2021.9.7. Both backups restores completed successfully but the same issue persists.

Any ideas ?

Same issue here after update of HASS and HA…? Already restarted twise… no change.
Don’t want to take over the thread, but guess might be the same issue… (else I’ll create a new one)

Running as VM in unraid.

Can’t read discover info:

i could fix it by connecting to the console and running “core update” - it looks like the core didn’t update correctly.

I had the same problem (I think?). When I tried ha core update, I was told that HA Core was already up-to-date. I have no idea what it does, but I blindly tried ha core rebuild and it fixed the problem for me. It’d be great if someone with more knowledge could say something about if that was safe or stupid.
If you’re on HassOS you should probably do that via the “Terminal & SSH” add-on, but you can also use the debugging SSH server if all else fails.
