AUTH_KEY_UNREGISTERED issue

[ali-ghamdan]

Everything is correct, and the server was working, and suddenly this issue appears, I restarted the server, and no hope.
I found this, it might be good: https://stackoverflow.com/questions/68410128/telegram-getting-auth-key-unregistered-and-api-id-invalid-errors

the detailed error:

RPCError: 401: AUTH_KEY_UNREGISTERED (caused by channels.GetChannels)

I didn't change anything after it runs correctly, then this appears after one day.
