You need to first change the connection from your old portal back to ArcGIS Online before trying to sign in. You can do this in Settings → Portals, then tap on ArcGIS Online to make that your active ArcGIS Connection. Signing in now will take you to the normal ArcGIS Online OAuth page and you can continue from there.
