Apple account linked to Xcode can't login. Always shows 503 error. Sometimes it login and loses the connection often.

Hey guys,

This is the first time I'm testing my app on the device after spending some quality time I completed setup but now I ran into below error.

It's so much annoying that the Xcode loses the connections anf thus throws error while running the below command

cordova run ios --device

I get the below error
