Floating IP problem



We have problem with challenge on Floating IP’s. Any help would be appreciated

Here are more info about it.

Server with HAProxy using acmetool listing on 402 as proxy. Both Public IP and Floating IP are assigned to HAProxy. On HAProxy request is proxied to 402 with acl (path_beg /.well-known/acme-challenge/ )

Public IP:
Floating IP: (with anchor IP of

domainA.com pointed to Public IP
domainB.com pointed to Floating IP


  • Both domainA.com and domainB.com is accessible on 80 and HAProxy proxies these to NGINX. So both domain is served over 80 with success.

  • domainA (on Public IP) SSL requests are signed with SUCCESS

  • domainB (on Floating IP) SSL requests are signed with FAILURE




What’s the failure message?

Thank you
