Minecraft error code glowstone

Hello there.

This bug is from minecraft 1.16.221 I guess and it keeps happening until I turn on my VPN.

I can't sign in using my own IP and I have to turn on a VPN

Also when I sign in using my own network after signing in using a VPN it still can't connect to Xbox live. What is this error code exactly?

Is this a bug? Or this is my network problem

Please check this. Thanks
