Hey there,

I use qbittorrent v4.5.2 on Kubuntu 22.04. It is working fine via ipv4. Concerning ipv6 qbittorrent cannot open a port, it says:

Code: Select all

22.03.23 09:22 - UPnP/NAT-PMP: Fehler beim Portmapping. Meldung: "could not map port using NAT-PMP[ipv6-adress-here]: not authorized"
Any suggestion?

o.k., I got it.

I had to deactivate privacy extensions.

Deactivate in Fritzbox 7460 the UPnP automatic port forwarding and also in qbittorrent.

Change manually in Fritzbox the interface id of my computer using the last 4 numbers of the ipv6 address, as :xxxx:xxxx:xxxx:xxxx (I didn't understand this, I just tried it....;)

Open ports manually in Fritzbox.

Restart qbittorrent.

ipv6 connection is working now, so this solved.
