Description

Hello,

I configured HTTP/3 for nginx 1.25. It's working when I call my website via curl. But it's showing here https://http3check.net/ that no connection could be established.

This is a clip of my conf file:
server {

listen 443 ssl;
listen [::]:443 ssl;
listen 443 quic reuseport;
server_name ...

http2 on;
http3 on;
http3_hq on;
quic_retry on;
ssl_early_data on;
quic_gso on;
quic_host_key /etc/ssl/..._2023.key;
add_header X-protocol $server_protocol always;

....

}
In the curl response it's showing:
HTTP/3 200
x-protocol: HTTP/3.0

But the browser check on https://http3check.net/ saying that it's not working.

Any idea for that?

Thank you!
Florian

Try adding add_header Alt-Svc h3=":443".

If it won't help, please post the debug log.
