OK, so here is what I did to get it working again (though, time will tell for how long it works):
* Deleted “Cloud Device” for my phone in the Cloud Access section.
* Created new activation code by clicking Get Code in the Cloud Access section.
* Tried to connect with mobile app using Manual Config option and entered new activation code.
Now, all is working again.
Note:
I also removed the port forwarding router entries I had created based on another discussion (they didn’t fix anything, so I cleaned it up)
I hope this helps someone.
