Sorry, it was solved and it was my problem. The explanation:
Haproxy make the checks with the name of the domain server, for example, if you have a backend with this line: server web1.servers 10.180.13.101:80 cookie A check inter 5s fastinter 1s downinter 1s rise 2 fall 2 The checks will be with the hostname, not with the ip. For this reason, in my particular case, i have a trouble.
