Can't log into mysqueezebox.com from LMS

Hi

I'm running Logitech Media Server on a sonicTransporter from Small Green Computer. Today I attempted to setup Spotify on it & could not get it to work. In the course of troubleshooting, I found that LMS was not logged into mysqueezebox.com. When I reentered my login credentials, LMS informed me they were incorrect, however I can successfully log into mysqueezebox.com using the same credentials. I even tried setting up a new mysqueezebox account using a different email address & experienced the same issue.

Does anyone know what it wrong?

TIA

Peter
