Because now correct syntax is another:
https://cbonte.github.io/haproxy-dconv/2.2/configuration.html#4.2-http-check%20connect

Now one backend can have more then one healtcheck and their types can be different and syntax now:

# check HTTP and HTTPs services on a server.
# first open port 80 thanks to server line port directive, then
# tcp-check opens port 443, ciphered and run a request on it:
option httpchk

http-check connect
http-check send meth GET uri / ver HTTP/1.1 hdr host haproxy.1wt.eu
http-check expect status 200-399
http-check connect port 443 ssl sni haproxy.1wt.eu
http-check send meth GET uri / ver HTTP/1.1 hdr host haproxy.1wt.eu
http-check expect status 200-399

server www 10.0.0.1 check port 80

I wrote in my ticket https://redmine.pfsense.org/issues/10739 that HAproxy 2.2 has changes in heatchecks that need to be aligned with pfSense plugin.

More over now HAproxy 2.0 support alpn h2 on backend and from 2.2 it supported on http-check. Also default server param would be cool to not copy paste all customization between 2-5 webservers
