I'm testing Debian 11 Bullseye with Apache 2.4.41 and I'm trying to activate HTTP2

I did some things :

sudo a2enmod http2

It returns : Module http2 already enabled

Then I put this line on my SSL/HTTPS virtualhost :

Protocols h2 h2c http/1.1

After having restarted the Apache service, my test is not Ok and returns HTTP/1.1 request. I tested with a curl command and via https://tools.keycdn.com/http2-test

Is there a problem with the version of Debian or Apache ? Or something else ?

  • Two things. Is the Protocols directive in the right spot? Is the SSL cipher strong enough? See https://httpd.apache.org/docs/2.4/howto/http2.html, "choose a strong SSLCipherSuite". – Gerard H. Pille May 19 '20 at 10:33
