Cant read supervisor data

I have sometimes the same issue.

Sometimes HASS works fine without issues for Weeks, and then suddenly sometimes, it seems like hass-core cannot connect to supervisor. Reloading supervisor does not help, only a restart of hass works. And this, you have to do from the commandline as the restart from developer-tools does not work.

This issue was mentioned by more users, but nobody found a fix for it, all the issues went stale…
