Waiting for Supervisor to startup

Issue 1: I had a successful install yesterday, finally after many many attempts. My laptop had a system update and when I went to launch HA, I’m faced with this. Any ideas where to go from here?
Issue 2: My chrome says “This site can’t be reached” help please and thank you.

Thank you in advanced.

Have you fixed this problem yet. I’ve got a similar problem where my HA says: “Waiting for Supervisor to startup…”
