Ran into the same problem after upgrading to Unraid 7.0.0 2025-01-09.
For anyone still not clear, you just boot into safe mode and will find out the SSH works again. Then, reboot into production mode and the SSH will be back to normal.
Same problem here. Seems the issue is still not fixed.
"Set warranty date entry:" is set to "Unraid", and tried "Force Scan All" multiple times, but the value is not read/write correctly. Maybe the API or something is changed.
