No newt connection possible from IPv6 only Client

[doklages]

Hi,
first of all, thank you very much for the great product :)

I have a problem with IPv6 only EndPoints. My pangolin Server itself is DualStack and also the docker proxy service is listening to IPv6 as well as IPv4. For the proxy Stuff everything is working as expected.

But when I bring up a new site in pangolin, the websocket connection is working as expected but the wireguard part is not working. In the logs I'm getting errors like:

Failed to send initial hole punch to IPV4_Adress: failed to write to UDP: write udp [::]:49468->IP_V4_Address:2182
SendMessageInterval timed out after 16 attempts for message type: newt/wg/get-config

Is there a special variable to set in newt so it is using the available IPv6 connection?

I also have retried this with a brand new install of pangolin server (IPv6 enable) but same result

Kind regards
Dominik
