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 ?
