I'm sorry, but I see nothing usable in your report. From what I understand, haproxy's health-checks sent to your servers report a failed server. There could be multiple causes, most common ones including missing object, server rejecting request for given URL or given source, and server expecting a host name in the request.

Could you please provide :

• your configuration
• the server's logs
• the output of a request sent by hand to the server, as would do haproxy.
• ideally, a "tcpdump -s0" capture of the requests/responses between haproxy and the server would help.

For the hand-crafted request, I think you'll simply have to telnet to your server's port and type "HEAD / HTTP/1.0" then hit return twice. The reply should be what haproxy gets.

If it is too cumbersome to configure both haproxy and the server to support HTTP health-checks, you can also fall back to TCP health checks (simply disable "option httpchk"). It will then just check if the server's port respond.

Hoping this helps,
