I've been running Teamviewer Host for Samsung on my Note 4 successfully for the past 2+ weeks. The phone is located halfway across the country and I was using my daily phone to monitor security and check the status of multiple online connections to this Note 4 through Host, but just yesterday the phone appears to have gone offline, or at least, it seems Teamviewer is no longer active on this phone. I know the internet is still working because there are other services that require internet access I can still connect to at that location and I can use Android Device Manager to locate the Note 4, but Teamviewer says it's offline.
Is there maybe some update or server issue that may have caused this? The connection had been rock solid up until yesterday and the phone is plugged in with 100% charge the last time I checked which was less than 24 hours ago, and this phone typically last weeks while idle so something definitely happened.
