Load balancer & http2

Laravel
#1

Is anyone able to shed some light on how to get the load balancer to server data via http2, all the requests are logging in the browser as http1

I have the ssl setup on the load balancer, and the laravel installed on 2 web servers.

Thanks

Hi Adam,

Thanks for the link - I have this setup already, I also tried several config variations too to see if there was an issue. Currently I now have it set to wildcard (allow all) and everything is still redirected through http1.1 - SSL is reporting OK??

Could it be a config issue somewhere?

I have also ran a http2 checker on the server - Http2 in not enabled???

Is it supported for load balancers?

Cleavr doesn’t enable http2 by default - we’d need to look at incorporating a checkbox or something in the UI during LB setup.

But, HAProxy does support it. To manually enable, you could SSH into the load balance server, find /etc/haproxy/haproxy.cfg then find the frontend section and add alpn h2,http/1.1 to the end of the bind *:443 line.

For example:

 bind *:443 ssl crt /etc/haproxy/ssl/<your domain>/<your domain>.pem alpn h2,http/1.1

Save and restart HAProxy.

Ahhhh! Thanks Adam. I thought I’d added that but I needed sudo access for it to take effect.

My preference would be for this to be the default - but a checkbox in the UI would be good too :slight_smile:

All working for me now!

in addition - if you’re going to work on this - adding h3 with QUIC support would be ace :wink:
