Could not connect to transmission

[BadderBlackBart]

Currently running Kodi Matrix 19.1 on a Raspberry Pi 3 running Arch. The add-on won't open.
My settings are localhost (the transmission daemon is running locally), port 9091 (which is reachable via web-interface). Username and password are disabled in the transmission-daemon.

Any ideas what might be the problem? There is the part of the log concerning the transmisson-addon. Thanks!

What happens if addon settings directory is removed? i.e /var/lib/kodi/.kodi/userdata/addon_data/script.transmission ?

[BadderBlackBart]

No change. I keep getting the same error. I tried putting in a username and password as a test but it changes nothing.

[basilgello]

I cant reproduce it with Python 3.9.2. But I assume Arch has 3.10 alreasy?

[BadderBlackBart]

The system has the 3.9.6 version installed
