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 4

    TCP: 3478, 3479, 3480
UDP: 3074, 3478, 3479

    Street Fighter 6 on PlayStation 5

    TCP: 3478, 3479, 3480
UDP: 3074, 3478, 3479

    Street Fighter 6 on Xbox Series X

    TCP: 3074
UDP: 88, 500, 3074, 3544, 4500

    Street Fighter 6 on Steam

    TCP: 27015, 27036
UDP: 27015, 27031-27033, 27034-27036

    i doubt that anything other than the ports listed under steam should actualls concern me,
    but the low port numbers 80 &500 seemed like potential snags

    i tried the following things:

    i added net.ipv4.ip_unprivileged_port_start=0 to
    /etc/sysctl.conf

    i 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?
