Connection/login timeout: timed out

[karnhack]

Hello everyone,
I use kodi 19 on raspberry pi 3 b+ and dietpi (without DE). I had problems using username/password, so I used NFAuthentication.key login.
The login procedure with NFAuthentication.key seems to have been successful (I am asked for the pin and then the password).
It seems to be loading but after a few tens of seconds the message appears: timeout: timed out ...

In the addon settings, I set the "results per page" from 90 to 45 but the problem still remains.
Thanks for the attention.
