First things:
Are you on the same local network as the AMP isntance?
Is your Minecraft console showing any entries that would suggest it failed to connect to mojang?

If you can reply with the containers network settings and your minecraft settings I can give you a hand. I’ve seen this error before but it was a one off and never came back!

I am in the same network as the server. And with (playit.gg) it does not funktionate too.
