GarageBand to SoundCloud credentials failed

Reprint from previous question:

I’m trying to upload a track to soundcloud(which i’ve done before) on an iPad pro. I for some reason cannot get into my soundcloud account via garageband. I have the sign in credentials in my saved passwords and they work fine directly on the soundcloud website and in the app. When I go to sign into the app THROUGH GarageBand however, I keep getting the message: “Ooops. Authentication failed. Please check your credentials and try logging in again.”

I’ve tried typing the credentials in manually as well.

The credentials are fine. What is the issue?
