Description

For Security reasons if port 80 is blocked in XenApp/XenDesktop Environments then starting XenApp/Xendesktop 7.12 Custom SDK Port can be configured for FMA services using the PowerShell Script provided in below article:

https://support.citrix.com/article/CTX232520

After configuring Custom SDK Port for FMA services we get an error "The System Is Currently Unavailable.Please Try Again Later Or Contact Your Administrator" after entering the credentials.

Director Error

Resolution


Specifying the Correct Custom SDK Port in “Service.AutodicoveryAddress” resolves the issue.

IIS

Problem Cause

  • Director fetches the information of Delivery Controller it needs to communicate with, via “Service.AutodicoveryAddress” application setting of Director site. In case we have specified a Custom SDK Port Example 8181 instead of default port 80, Director will fail to communicate with Delivery Controller because if the custom SDK Port port is not specified in “Service.AutodicoveryAddress”.
  • DirectorService will gives an exception in CDF Traces as shown below. This is because by default Director tries to communicate with Monitor Service over port 80 and Monitor Service but in this case it is actually listening on custom SDKPort 8181.
