Hi, try set Host header :)

option httpchk GET / HTTP/1.1
http-check send hdr Host domain.com
http-check expect status 200
server www1 10.0.0.10:9000 check

I have multiple server, then how can I give static Host header? This is working for all other application , I have only issue with Cerebro My config

backend cerebro cookie JSESSIONID prefix http-check disable-on-404 option httpchk HEAD /cerebro server server-host xxx.xxx.xxx.xx:8081 cookie server-host check server server-host1 xxx.xxx.xxx.xx:8081 cookie server-host1 check
