Android: Connection could not be established
I've installed the TeamViewer app in my android tablet, (Samsung Note Pro12.2 SM-P900), however, it never seems to be able to connect to teamviewer at all. On the Connect page, entering a valid TV ID results in the message "A connection could not be established. Please check your connection and try again". Similarly, on the Computers tab, entering my user name and password results in "Sign in failed. Please check your connection and try again". The tablet is definitely online, and I have tried reinstalling the app but to no avail. I can confirm that I have also tried the above on my mobile device and that works fine on cellular data and Wi-Fi. What can I do to fix this issue? Thanks!
