[HAProxy 2.2.2] http-check send meth OPTIONS failure

The http-check send meth OPTIONS directive is not working correct. I got a L7RSP with response: TCPCHK got an empty response at step 2. However, if I use GET instead OPTIONS I will get L7OK. This problem only occurs in the latest version.

Of course if I use curl I will get correct response, so it’s not backend server side issue.

My HAProxy 2.1.8 Config:

listen tcp_async_pg_cluster
  bind 0.0.0.0:5432 
  mode tcp
  default-server check check-ssl verify none port 8008 inter 3s fall 3 rise 2 on-marked-down shutdown-sessions
  http-check expect status 200
  maxconn 100
  option httpchk OPTIONS /async
  option tcplog
  option dontlog-normal
  retries 2
  server pg1 pg1-cluster.example.com:5432
  server pg2 pg2-cluster.example.com:5432
  server pg3 pg3-cluster.example.com:5432

and config of HAProxy 2.2.2:

listen tcp_async_pg_cluster
  bind 0.0.0.0:5432 
  mode tcp
  default-server check check-ssl verify none port 8008 inter 3s fall 3 rise 2 on-marked-down shutdown-sessions
  maxconn 100
  option httpchk
  option tcplog
  option dontlog-normal
  retries 2
  http-check send meth OPTIONS uri /async
  http-check expect status 200
  server pg1 pg1-cluster.example.com:5432
  server pg2 pg2-cluster.example.com:5432
  server pg3 pg3-cluster.example.com:5432
