App Exchange Not Working

My App Exchange does not work and I’m trying to figure out why.  I hit the Get Started and it starts doing its thing and then I get this Error Messages: Failed SOC Check Unable to get SOC Information 213.

I check the Preflight Progress, and all checks except the SOC Check.

Also this morning, I’m having issues with my App: Service Unavailable.  F451: Uh-oh looks like we have our wires crossed.  Try again.

Anyone else having these issues?

I have the Samsung 22+
