I have haproxy installed, doing http/3. The http/3 is working for
almost everything. I build it from the main branch and update it fairly
often.
One of the websites I have behind it is my gitlab server. That is
always http/2, it never switches to http/3.
Does anyone know why that happens, and whether there is anything I can
do about it? The alt-svc header IS received by the browser.
