All my backends support h2. http health check is failing as it is using h2 and marking the members down. If I remove the health check then everything works fine .
How do I force the health check to happen on http/1.1 instead of h2.
option httpchk GET /healthcheck HTTP/1.1
server default_1_java 18.104.22.168:443 check ssl verify none alpn h2,http/1.1 server default_2_java 22.214.171.124:443 check ssl verify none alpn h2,http/1.1
