HTTPS and Load balancer issues

Posted on by Microsoft Employee

Hello fellow CRM people! 

I am facing a classical problem that I've successfully sorted out numerous times before, but for some reason I am bit stuck on this.

I have 2 CRM servers (front end and full server) on premise. Trying to enable HTTPS and then point the deployment manager to a load balanced URL.

I have so far:

1. Set up the load balancer to route traffic to the servers (done by 3rd party actually)

2. Installed the SSL certificate on both servers (front and full - also done by 3rd party)

3. Changed the bindings of the CRM site on both servers so that it:

* uses the installed SSL certificate

* updated the deployment manager URL to (I've attempted a few configurations as per below, but what I have it as right now is the last one)

- changed to https

- changed to https and added 443 port

- changed to https and FQDN + port

- changed to https, load balancer URL + port and ticked the "this deployment uses an NLB"

After restarting IIS, browsing to the below URLs NOT from the server results in:

* https://serverName1 (full server) - getting a certificate error, but able to browse the app after ignoring it

https://serverName2 (web server) - getting a certificate error, but able to browse the app after ignoring it

* https://loadBalancedURL.FQDN:443 -getting a certificate error, but able to browse the app after ignoring it

Browsing from the server results in:

https://serverName1 (full server) - getting a certificate error, but able to browse the app after ignoring it

https://serverName2 (web server) - getting a certificate error, but able to browse the app after ignoring it

https://loadBalancedURL.FQDN:443 - getting a certficate error, when clicking on ignore and continue I am asked for credentials 2-3 times and then getting 401.1

The AppPool is running under a service account. I have NOT changed the SPNs registered since carrying out the installation.

We are NOT looking to do claims based or IFD - just need it https and load balanced

Your help is appreciated!
