Problem while publishing my xamarin IOS app on Visual Studio

Hi everyone, usually i used to work on my xamarin application from a windows OS using Visual Studio application. When testing IOS apps i used to connect to macbook that my boss has to my windows pc. Nowdays i have a big problem while i try to publish an app. I select Release configuration, rebuild the project and in this case it asks me to login in with my Apple developer account but i always get an errore:

'There is an error while trying to access the auth service is not available'

Does anyone know a different way to publish an IOS app? I really do not know what to do.

This is my first time trying to publish an IOS app..

This is what i am tryng to do
