--- Comment #3 from Brendan Shanks <bshanks at codeweavers.com> ---
Does Manjaro/Arch define the local hostname to be '127.0.1.1' in /etc/hosts?
If so, can you try commenting out the line and then testing GTA V?

Debian/Ubuntu do this (see
https://www.debian.org/doc/manuals/debian-reference/ch05.en.html#_the_hostname_resolution),
and I think it may be causing this issue.

GTA V calls getaddrinfo() with the local hostname (returned by gethostname()),
and on my Ubuntu system this returns only '127.0.1.1'. GTA V shows this as the
"local IP" in the Social Club overlay->Settings->Network, and I suspect it's
trying to use it for network listening.
With the '127.0.1.1' line commented out in /etc/hosts, GTA V at least shows the
correct local IP.
