I recently started playing sf6 in online mode.
Playing against other pc users seems to work just fine,
however Crossplay matches fail with the error code 50200-21018
(as far as i understand the first digits designate the http status code 502)
I talked to a steamdeck user for which crossplay worked just fine I play on silverblue using the flatpack version of steam.
At first is Suspected problems with the proton version,
and tried several diffrent versions (including GE)
However this did not help.
Updating my ostree and flatpacks did also not help.
does anyone have suggestions on what might be causing these issues, or how to debug it further?
EDIT: same error occured when i tried using the steam version from the os
quick update:
i learned that sf6 uses the following ports:
Street Fighter 6 on PlayStation 4TCP: 3478, 3479, 3480 UDP: 3074, 3478, 3479Street Fighter 6 on PlayStation 5
TCP: 3478, 3479, 3480 UDP: 3074, 3478, 3479Street Fighter 6 on Xbox Series X
TCP: 3074 UDP: 88, 500, 3074, 3544, 4500Street Fighter 6 on Steam
TCP: 27015, 27036 UDP: 27015, 27031-27033, 27034-27036i doubt that anything other than the ports listed under steam should actualls concern me,
but the low port numbers 80 &500 seemed like potential snagsi tried the following things:
i added net.ipv4.ip_unprivileged_port_start=0 to
/etc/sysctl.confi added entries for the ports 0-1024 for tcp & udp to my firewall.
these things did not help.
i also tried to set up port forwarding,
where i found out that it would not let me set external ports outside of the range 8044-8063.i assumed that my provider might be doin weird stuff that was causing the issue.
but if that was actually the case,
why would the windows version work?resolved
i found the following guide on reddit:
Bro just disable ipv6
i followed the instructions and it worked
