Sorry to hear about what's happening. There was a SiriusXM outage a month ago that was causing issues with customers, but that has since been resolved by SiriusXM and should no longer cause any issues.
Could you try removing and re-adding your SiriusXM account to your SoundTouch App?
Does this help? Does it resolve the issue?

just being able to listen to Siriusxm in the US and Canada is only correct for the xm-radio's like in a car.
Online, you can listen anywhere in the world.
At this moment, I have no problem listening to Siriusxm on my pc or tablet.
Loggin in to my account on my Bose soundtouch system is still impossible: error 6027.
Listening to Siriusxm through Bose Soundtouch was perfect possible until early november (if I remember well).
Still waiting for a solution....

Thank you for your post. Even though some music services may be available in many more countries on their own, they are not all currently able to be used as a streaming service using SoundTouch. Please click here for the full details on SoundTouch music services availability.
