Cannot connect to nextcloud desktop client

I am using manjaro, I can connect to my nextbox using gnome setting>online accounts and also on an android phone using the nextcloud app. However when I try to connect to the desktop client installed on the manjaro machine I get this error:
Schermata da 2021-10-30 10-15-24

it’s not in english, but I hope someone will understand…

I just tested, I can access my nextbox with the same desktop nextcloud client with a pinephone, may it be some config of firewall on the pc?

I fixed that, no idea why the config file of nextbox client had tor proxy info, I delete the wrong info and now it works!
