Browser doesn't show h3 protocol

Hello,

i set up a website with this docker container as base image. everythings working fine so far. Except that somehow all browsers are still connecting with http2 (tested with latest chrome and latest firefox - http3 is enabled in all browsers - this was verified on https://quic.nginx.org/).
https://www.http3check.net/ and curl with forced http3 are showing that my website is correctly set up with http3. i also created a separate example with caddy and there the browsers are showing http3 correctly.

is this a known "issue" of this project?

Thanks

Same here, it is working when forced, but not in the Browser:

$ docker run -it --rm ymuski/curl-http3 curl -I --http3 https://xxxxx.xxx
HTTP/3 301
server: nginx
date: Sun, 06 Jun 2021 08:33:50 GMT
content-type: text/html; charset=UTF-8
vary: Accept-Encoding
x-powered-by: PHP/7.4.19
alt-svc: ma=86400,h3=":443"; ma=86400,quic=":443"

@pako88 @der--flo Please try with latest image.

No luck for me.

btw. your readme tells "Alpine Linux image with nginx 1.19.5 (mainline) ", but in the Dockerfile you use "ENV NGINX_VERSION 1.16.1"

built it with

ENV NGINX_VERSION 1.19.5
ENV QUICHE_COMMIT 6d070ed8694216806f3ce689d71ceb7ad76d425e

now it works with Firefox 89 and Chrome 90.0.4430.212

@der--flo the quiche H3 doesn't work with nginx 1.19.5. I have moved nginx to the latest supported version which is 1.16.1. H3 should be working now and I see your latest edit now saying it is working for you.

still no luck for me. Latest version in repository and changes from @der--flo are both not working for me

Please try again with this header in 8ef7b85597ca3b2d2127352c746c3fe041450185.

I have exactly same problem. It works well with cURL, but not with browsers... So, any solution?

With 8ef7b85597ca3b2d2127352c746c3fe041450185 applied in your nginx conf it is still failing?

With 8ef7b85 applied in your nginx conf it is still failing?

Yes Anyway I have changed little bit to get it working: add_header alt-svc 'h3=":443"; ma=600,h3-29=":443"; ma=600,h2=":443"; ma=600,quic=":443"; ma=600; v="46,43"';

seems like h3-27 and 28 are not supported anymore with latest Chromium-based releases
