Exchange 2013 SP1 OWA the page can't be displayed issue

Question

OWA the page can't be displayed
Hi,  i've Exchange topology (upgraded from 2007 one server)
2 CAS servers NLB with VIP 172.16.0.98
2 MBX Servers DAG with DAG
using Cisco ASA NAT public IP for example 9.9.9.9 ....> 172.16.0.98
i've created split DNS zone for public domain in internal DNS to unify URLs internal and external Mail.Domain.Com
i've created internal zone called Mail.Domain.Com and Autodiscover.domain.com point to VIP 172.16.0.98
Everything is OK but sometimes users report when they access OWA from inside or outside when user submit user/ pass faced error  the page can't be displayed?
i tried this this user from different browsers and different computer the same issue 
if i tried another user from the same computer it works fine
the strangest point after 30-60 minutes it backs to live and everything going fine
i checked event viewer there is nothing related to this issue.
in sometimes if i tried to access manual to CAS1.Domain.Local / IP address/ owa it works fine.
 URL changes to https://Mail.Domain.Com/owa/auth.owa
i red some about putting my public domain as remote domain but it's not clear !
any ideas please?

If it works properly when connecting directly to the server, then something is misconfigured in the load balancer or something else in that data path.

Thanks Ed, 
NLB converged is OK. and all users are running well, except while this issue accrued.
i checked event viewer under exchange managed availability
