Storefront 2203 - Citrix XML Service Errors


sortola27

Question

We're seeing multiple repeating errors in event viewer from the Citrix XML Service in our CVAD 2203 LTSR enviroment.  We have 2 storefront servers.  01 is not showing the errors, but 02 is. 
We're running into an issue were people are getting "no available desktops" at login and believe this is the cause, but we're running into walls trying to figure out why.

ERROR - The Citrix XML Service at address [UnknownRequest] does not support capability integrated-authentication.

ERROR - All the Citrix XML Services configured for farm KS-NewPool failed to respond to this XML Service transaction.

ERROR - The Citrix XML Service object was not found: 404 Not Found. This message was reported from the XML Service at address http://ks-ctxdc02.DOMAIN.internal/scripts/CtxIntegrated/wpnbr.dll. The specified Citrix XML Service could not be contacted and has been temporarily removed from the list of active services.

Then will see these two information entries and then the XML errors repeat about a few minutes later.

I believe this update was also already installed:
https://support.citrix.com/article/CTX457757/hotfix-receiver-storefront-3231-for-citrix-virtual-apps-and-desktops-2203-english

Citrix Storefront installed version shows as: 2203.0.1.2

We've also look at these KB fixes, but did not help:

While we're at CVAD 2203 LTSR now, we do still have a lot of PC's running Citrix Receiver 4.7 if that could be a part of this as I noticed this bit of info from
https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/2203-ltsr/removed-features.html

Quote

StoreFront support for TLS 1.0, and TLS 1.1 protocols between Citrix Virtual Apps and Desktops (formerly XenApp and XenDesktop) and Citrix Receiver, and Workspace Hub.
Removed in 2203
Upgrade Citrix Receivers to a Citrix Workspace app that supports the TLS 1.2 protocol. For more information on Citrix Workspace app, see https://docs.citrix.com/en-us/citrix-workspace-app.



Thanks.

The last thing I have in my notes about this was a registry change suggested by support.  Seems after we did this it stopped:

Please do the following registry changes to all the Delivery controller or the affected ones in this case.
Note: Before doing any changes to the registry, Please take a snapshot of the VM
Reg edit : HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\DesktopServer
"XmlWpnbrRequestTimeoutMs" to 120000 to increase the timeout duration.
Please reboot the Delivery controller one by one to see if the issue gets fixed. Reboot is must to reflect changes on all Delivery controller
