http2 on; doesnt work as expected

[skullcrushercmd]

spent a while figuring out how to enable http3 with http2 and below with and without ssl encryption (http and https), when i use listen 80 http2; it works fine (on http but i didnt set it up for ssl so expected) but http2 on; doesnt work at all, below is one of my working configs without the extra ssl encryption

server {
listen 443 quic reuseport;
listen [::]:443 ssl;
listen 443 ssl;
listen 80 http2;
ssl_early_data on;
server_name gpt.anyvm.tech;

location / {
proxy_pass http://localhost:3001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
add_header alt-svc 'h3=":$server_port"; ma=1800';
add_header x-quic 'h3';
proxy_cache_bypass $http_upgrade;
}

ssl_certificate /etc/letsencrypt/live/gpt.anyvm.tech/fullchain.pem; # managed by Certb>
ssl_certificate_key /etc/letsencrypt/live/gpt.anyvm.tech/privkey.pem; # managed by Cer>
}

server {
if ($host = gpt.anyvm.tech) {
return 301 https://$host$request_uri;
}
listen 80;
listen [::]:80;
server_name gpt.anyvm.tech;

}

Hi, you have reached the bug tracker for NGINX Unit (not nginx the web server)... You should perhaps try asking on the nginx mailing list instead... thanks!
