Hello,
I have installed Hassos in Virtualbox, originally it was version 4.5, later I have successfully upgraded to 4.6, however when 4.7 became available, I couldn’t upgrade, since after upgrade everything seemed to be fine, only the web interface was not working. In the Home Assistant log it looked like everything was fine, no errors at all and everything was working, I could even see my automations working. Restart didn’t help. Today I have tried to upgrade to 4.8 which just become available and the result is the same web interface does not come up after upgrade.
Any advice on what can be wrong or how can I fix it? I had to revert back to the previous version (since it’s running in Virtualbox at least it’s easy to restore from the snapshot).
