503 Error On hosts.map Config

Help!
1

Hi Guys & Girls,

Hoping someone can point me in the right direction:

We’re receiving a 503 error when we try to connect to a server (full details below) whose access is controlled by haproxy and a server map. However, if we connect to the backend server directly then everything is aok - so we think the error is in the haproxy conf file and/or the map file.

Any help would be greatly appreciated.

The servers:

  • server1.domain.local - working fine
  • server2.domain.local:5000 - working fine with direct connection
  • server3 - alias for server2 but without the port (ie server3.domain.local:80)

The map file (hosts.map):

#front-ends             #back-ends
server3.domain.local    server3-redirect
doamin.local            www-servers

The haproxy conf file (relevant parts):

frontend www
        bind *:80
        bind *:443 ssl crt '/etc/haproxy/ssl/*.ourdomain.com' crt /etc/haproxy/ssl/ ecdhe secp384r1 alpn h2,http/1.1
        acl acl_plain_http ssl_fc,not
        http-request redirect scheme https code 301 if acl_plain_http
        http-request redirect prefix http://www.ourdomain.com code 301 if { hdr(host) -i domain.com }
        http-response add-header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload;"
        http-request set-var(txn.host) req.hdr(host)
        use_backend %[req.hdr(host),lower,map_dom(/etc/haproxy/maps/hosts.map,www-servers)]
        default_backend www-servers

backend server3-redirect
        mode http
        option http-server-close
        cookie SERVERUSED insert indirect nocache
        http-request set-header X-Forwarded-Port %[dst_port]
        http-request add-header X-Forwarded-Proto https
        server server3 server2.domain.local:5000 cookie server3 check

backend www_servers
        mode http
        option http-server-close
        cookie SERVERUSED insert indirect nocache
        http-request set-header X-Forwarded-Port %[dst_port]
        http-request add-header X-Forwarded-Proto https
        server server1 server1.domain.local:80 cookie server1 check
