First - congrats on the release !
Looks like when I fire up the new release (this is on latest Catalina - 10.15.4) - there is a UPnP request (IGD2) that looks like it "mangles" my IPv6 address into something like an IPv4 address / field.
My firewall log shows this:
Code: Select all
May 23 13:17:13 ice miniupnpd: Failed to convert hostname '2607:fcc8:8ac2:a' to ip address May 23 13:17:13 ice miniupnpd: Failed to convert hostname '2607:fcc8:8ac2:a' to ip address
Here is a screenshot from Wireshark showing the offending request:
The IPv4 mapping (NAT-PMP) works just fine by the way.
PS: I have a pcap as well if any developers want me to share privately - let me know how to get it to you. I managed to filter and just catch the UPnP conversation and you can see the request and the (code 500) error from miniupnpd.
