Exchange 2010 and setup through haproxy

Hi, I was wondering if someone can point me in the right direction of resolving an exchange CAS server setup. When using owa we receive error “The custom error module does not recognize this error” has anyone come across this before? We have replaced an old TMG with pfsense and haproxy integrated. Thanks

My config below
