Notes from the lab: Citrix StoreFront 2203 and the cannot complete request

A quick blog regarding my Citrix lab upgrade from Citrix Virtual Apps and Dekstops (CVAD) 1912CU4 to 2203 and the little StoreFront snag I hit.

Summary of my setup:
Two Delivery controllers
Two StoreFront servers cohabitating with Director as well
Two FAS servers
Two WEM servers
One unmanaged VDA worker

And a Citrix ADC HA setup load-balancing the entire solution with keep in mind only TLS1.2 enabled for the services.

All components went flawless through the upgrade only after the maintenance window I could not see any desktops when logging in through StoreFront and got the dreaded “cannot complete your request” when logging in via the Citrix Gateway. At first no error entries that would stand out not even the errors shown in the support article which I’m mentioning in a bit.

The I remembered that there was a hotfix released quite fast after the original 2203 release of StoreFront regarding TLS hardening of the original CVAD setup. The following articles mention it in detail:
Gateway Callback and / or XML Communication fails after upgrade to Storefront 2203
Hotfix – Receiver StoreFront 3.23.1- For Citrix Virtual Apps and Desktops 2203 – English

After doing some checks regarding the XML, StoreFront and all the VIP’s this was definitely the case. The event logs would make clear that the XML could not be reached and when logging in through the gateway the callback URL would not be reachable. Updating the StoreFront servers with the above hotfix resolved everything.

Hope it helps!
