I see, thanks. It's so badly broken without the reuseport parameter that I think using multiple workers with quic should imply reuseport, or at the very least raise a warning in the logs if an attempt is made to use such a configuration. ___ nginx mailing list nginx@nginx.org https://mailman.nginx.org/mailman/listinfo/nginx

This is just due to limitations of how UDP (being stateless and sessionless) is handled by the kernel compared to TCP (which is session orientated).

How important is the "reuseport" flag for quic?
I'm using nginx 1.26.1 from the nginx.org ubuntu repo. I find when I remove the "reuseport" flag from the "listen" directive for my quic port, a lot page assets fail to load, and the browser ultimately falls back to http/2. When I re-add "reuseport", all http/3 requests succeed again. How crucial is "reuseport" when using quic on nginx? Is it normal for things to break badly without it? ___ nginx mailing list nginx@nginx.org https://mailman.nginx.org/mailman/listinfo/nginx
