Hi,
since a few weeks, my push registration is very buggy.
I can see all incoming sms on desksms.appspot.com, but if i reply to them, the status is pending for a long time and than the status get failed.
I found a workaround: Open Desksms on my phone, "Switch Account", select same account, than push-notifications will work for a short time, also pending sms will be send immediately.
Sometimes while reselecting my account i get this error:

How can i help to debug it a bit better?
Best Regards,
Johannes
