I installed adddon on my server and scanned QR code. When i try to enable 2fa i enter my password and the code on my mobile phone as token. But then nothing happens (no error, or confirmation). I tried to enter wrong password, which gives error but entering correct data doesn't do anything.
Server is on debian 9, nginx 1.10.3, php 7.0.19-1
Folder has the appropriate permission.
Any idea?
