I'm using an old tablet with android 4.4.2 to run the vrm app which displays my system in my control room. A couple of days ago the tablet stopped showing any details on the vrm app. Tried to log out / in but am getting an error: unknown error, please try again in a few minutes. This error shows at the app login and at the login to the vrm portal through a browser.
I have also created a new admin account and tried to log in, this also did not solve the issue, same error message.
Tried on a different system and works perfectly there, so the problem only persists on the android tablet on both the vrm app and through the vrm portal browser login.
