Storefront CU4 Upgrade at the weekend has thrown some spanners at my head

So I upgraded the Netscaler to 12.1.51.19 and the rest of the infrastructure to 7.15ltsr CU4 at the weekend.

 

Externally everything works fine but internally I am getting :

 

Attempting to launch application gives the error message  : " Cannot start App"

Storefront Reports the following error :" An SSL Hostname is required but none was supplied "

Event Viewer on the Storefront shows:

Citrix delivery service error 29 - Failed to launch the resource 'XenApp76_Controller.LabTech Control Cen'. An SSL hostname is required, but none was supplied by the farm 'XenApp76_Controller'.

 

Now Internally I don't have SSL enabled on the Delivery Controller so I looked at the guide here:

 

https://support.citrix.com/article/CTX225849

 

But I am still none the wiser as everything checks out. I have no idea why the apps internally are trying to use SSL.

 

Brokerservice shows :

SDK Port: 80

VDA Port: 5000

StoreFront Port: 80

StoreFront TLS Port: 443

Log File:

 

Everything else looks O.K 

 

I can only imagine I am missing something simple here as I inherited this system and maybe a storefront setting was customised or the like.

 

Thanks in Advance

So I found my answer in case anyone has the same.

 

There was a custom change to the ICA client configs made by the previous admin which caused it to point to the wrong place when storefront overwrote the old settings in the upgrade.
