I'm wanting to enable http/2 on our server but can't find the settings in webmin.

When I check the network tab of a site, it is showing the protocol as h3-29 which leads me to think that http3 is actually being used.

When i go to https://http3check.net/ though it shows "QUIC connection could not be established" and the header being served using http/1.1

https://www.getpagespeed.com/ shows http/2 not supported.

Totally confused. can someone please point me in the right direction? I;ve read the docs but they don't line up with what i see in admin.

Thank you.

ok, I have solved this. There is something missing from the docs. So, not only do you need ot open :443 in UDP_IN and UDP_OUT but ALSO in UDP6_IN and UDP6_OUT.

Updating this in the docs might save others many many hours in testing and debugging.
