Describe the Bug

Even with the "Address Family: IPv4+IPv6" configuration, Sunshine doesn't communicate through ipv6. If i do sudo ss -tulnp | grep 47989 or any other sunshine port it only shows a ipv4 entry. (I am with ipv6 enabled on the system and this was tested in both stable and beta releases)

Expected Behavior

Sunshine connecting through ipv6.

Additional Context

I have a CGNAT ipv4 block on my network but ipv6 works fine so i would like to use it
