Hi, this is my problem:

Until last week I was able to manage my router MR600 from remote by tether cloud app. Then I started to see the message Dispositivo Cloud (offline) and cannot connect any more. 

Today I went to the router place, and from wifi connection tether works fine (same phone ) . From remote is offline. 

I tryed to:

-reboot the router 

-Change TP-Link ID password from PC connection to the router and from Tether. 

-Uninstall and reinstall the tether app. 

Nothing change. From wifi ok, from remote by theater cloud no. 

Any Suggestion? 

Now I can't go physically back to the router place for some months. 

Thanks
