                          I'm trying to configure a load balancer between 2 servers with HAPoxy, this is my configuration:

    frontend haproxynode
        bind *:443 ssl crt /etc/ssl/private/isel.pem alpn h2,http/1.1
        mode tcp
        default_backend backendnodes
        
     backend backendnodes
        balance roundrobin
        option forwardfor
        server node1 192.168.1.5:80 check
        server node2 192.168.1.6:80 check

This is my network:

I'm running a word press server in both server VM's. And I'm using h2load to do the benchmarking.
When I use the command h2load -n 30 -c 30 https://192.168.1.26/blog/  I get this:

As you can see the application protocol is h2, but in WireShark the requests appear as HTTP 1.1, why?
