hello, we just set up HAPROXY on a CENTOS server. Our problem is that we are not able to reach our web application under Windows server 2012R2 We get an error “SOCKERR in 0ms”, I see that the HAPROXY server reaches the WIndows server but no TCP connection seems to want to open.

We checked the firewall and everything seems to be well configured

Do you have ideas of where could be the problem?

We use HAProxy on TCP Mode

Thank you

We found the solution

Our server Windows server block the SSL 3.0 and in the haproxy config the command option ssl-hello-chk use it for the “check”

We simply remove the option ssl-hello-chk.
