Frontend doesn't come up after OS 16.3 to 17.1 Update

I’m using the ova version of HA in Virtual Box in a Linux host.

After upgrading to 17.1, cli and Supervisor started, but the Frontend didn’t. I was not able to connect the browser to my URL, “not reachable”. After waiting 30 minutes or so I decided to fall back to slot A, and it worked again as before.

Any ideas or experiences with this issue?
