On upgrading an android phones WebView to be powered by Chrome 76, we found that we started getting connection errors when trying to log into an app.

The solution for this is to close the application and reopen it.

The issue is detailed here:  https://bugs.chromium.org/p/chromium/issues/detail?id=991107 and we are keeping an eye on it.

This issue has been solved in an update to the Android WebView, more information at:  https://bugs.chromium.org/p/chromium/issues/detail?id=991107
