I would be happy to help in any way with figureing this out. I am a Tech Advisor for a software company that troubleshoots high level excalated calls all day. Please check your internet connection and try again'

I will then see the normal login page on the Computers tab but when i enter my credentials i get, as stated above, 'Operation Failed.

none of that matters when i go back onto the teamviewer app over LTE I will get a blue window with nothing on it on the computers tab of the teamviewer app. I can turn off my phone or go on airplane and back or close the app or double tap home and slide the app up close. If I close the connection (that i activated over wifi/4g and swapped over to LTE) then it brings me back to a blank blue computers screen in the teamviewer app. If I gain an active connection to a remote PC through the app over wifi or 4G and then switch my phone back to LTE the connection stays active and I am able to manipulate the remote PC without any time out. If i turn off LTE in settings > Cellular > Cellular Data Options > Enable LTE > Off and force 4G everything works. When I try to log into my account over wireless LTE I see 'Operation Failed. I cannot confirm if I have the same Teamviewer Build that it worked on as my phone auto updated IOS apps. (not saying thats cause, just that it started after that) Teamviewer has always worked for me on my current phone, current, IOS, and current carrier before.

This all started after that last server downtime/update teamviewer announced. I am using LTE wireless data (this seems to be important) My hotspot is not on. I have version 6 CL of the IOS App for Teamviewer.
