Exchange 2013 OWA webpage keeps reloading - looping

OWA has me looping; i dont get a failure expect that the page loads.  i checked my virtual directories in IIS and verified that the SSL certificate was bonded to SMTP and IIS.

specifications
Exchange 2013 CU21
Server 2012 R2

there are two cas servers
CAS01 and CAS02

CAS02 is where  the problem lies as it loops from localhost there.  

DNS is correct all the way through.

Go to IIS
Check that the FrontEnd SSL Cert in "Binding" is the same on both (Front End and Backend)

Just like this:

On both CAS.

Jose,

I checked and they are the same on both CAS servers.  

i believe it has something to do with the URL's...is there a way to reset IIS?

Also - im getting a too many redirects error


and.....each time i put in my username and password it tells me wrong username and password (which it is not)
Check SCP script
https://gallery.technet.microsoft.com/office/Script-to-configure-the-5a58558b
Option -Get

if required to set use:
-set -urlpath "https://mailserver.domain.com"
i ran your script and they all appear to be correct and i have been running something similar that i found online as well.  (attached)

backtracking, this all occurred when i upgraded to CU22 on CAS02 server and initially,  before the upgrade, it was changing http redirection.

It could because of a few things.

1- DNS are not pointing correctly and thus keep loading until it reaches the timeout limit.
2- The virtual directory has a different name which is not related to your DNS.
3- The certificate was only applied to one server but not to the other server.

Do you have both servers in the same premises or diff location?
