Site isn´t served as HTTP/2

(Daniel Julius) #1

Hey Guys,

I´am using Caddy, but my site is serving over http/1.1. But i dont know why…
H2 is the default for Caddy, or?

In my Configfile i have add following keywords:

tls EMAIL {
alpn h2

Have everyone an little hint for me?

Thank You

Does that still happen if you take out the alpn line?

What is your full, unredacted Caddyfile? And how are you running Caddy?

(Daniel Julius) #5

Here is the Caddyfile…


You can test it on

I´am running Caddy on Debian 9 as a Service:

ExecStart=/usr/local/bin/caddy -log stdout -agree=true -conf=/etc/caddy/Caddyfile -root=/var/tmp
