After firmware update (v03.03.01-156) - Unable to access device (0)

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.
