Launch of Citrix-published Resources Fails if XML Port is Set Incorrectly

Launch of Citrix-published resources from a Citrix 7.x or 6.x server farm fails if the XML Port is set incorrectly in Workspace ONE Access.

Problem

Launch of Citrix-published resources from a Citrix 7.x or 6.x server farm fails if the XML Port is set incorrectly in Workspace ONE Access.

Solution

Ensure that the XML port is set correctly.

In a XenApp 6.x or earlier environment, ask the Citrix administrator to run CTXXMLS.EXE to verify the port or browse to the following location within the registry on the XenApp Management server:

HKLM/SYSTEM/CurrentControlSet/Services/CtxHttp | TcpPort=

Verify the port number. By default the port is set to 80, but it is commonly changed to 8080 or 88. Ensure that the correct port is set in the Workspace ONE Access Citrix configuration in the Catalog > Manage Desktop Applications > Citrix Published Application page.

For XenDesktop 7.x, see https://support.citrix.com/article/CTX127945 for information on verifying the XML port.
