After upgrading CWA Windows to 2409, if any PNAgent stores are configured (e.g., https://url/citrix/store/pnagent/config.xml), CWA shows an error message on refresh or sign-in stating, “To resolve this issue, contact your helpdesk with this information: Error while parsing.”

The solution is to move to Storefront instead of using the PNAgent store. The steps to migrate depend on the following:

• How the PNAgent store was configured (GPO, manual, or through installer) 

• If it’s a HTTP only store

• If Domain pass-through is enabled
  
  

1. Store config:
   

GPO: If the PNAgent store was configured using GPO, remove “PNAgent” URL from GPO settings and use store discovery URL, for example https://url/citrix/store/discovery.

Below are the steps to change the GPO:

• • Open the Citrix Workspace app Group Policy Object administrative template by running gpedit.msc.

  • Under the Computer Configuration node, go to Administrative Templates > Classic Administrative Templates (ADM) > Citrix Components > Citrix Workspace > StoreFront.

  • Select Citrix Gateway URL/StoreFront Accounts List.

  • Select the Enabled option and click Show. If you enable this policy setting, you can enter a list of StoreFront Accounts and NetScaler Gateway URL.

  • Enter the URL in the Value field.

  • Specify the store URL that is used with the Citrix Workspace app:
    STOREx="storename;http[s]://servername.domain/citrix/<storename>/discovery;[On, Off]; [storedescription]"

Manual: If the PNAgent store was configured manually, then the user has to 

• • Either manually remove the store or select ‘Reset Workspace App’

  • Add the storefront URL. For example https://url/citrix/store/discovery

       Two options are available if the store was configured using the installer command line.

Option 1:

• • Uninstall the existing version. 

  • Install with the store added in the cmd line as mentioned in https://docs.citrix.com/en-us/citrix-workspace-app-for-windows/install.html#examples-of-store-configuration-using-command-line-installation 

Option 2:

• • You can use cleaninstall parameter as mentioned in https://docs.citrix.com/en-us/citrix-workspace-app-for-windows/install.html#command-to-cleanup-and-install-citrix-workspace-app to combine both the steps above

2. HTTP Only store:

 If you are using HTTP only URL, then follow the steps mentioned in the article - https://support.citrix.com/s/article/CTX134341-how-to-configure-citrix-receiver-for-windows-to-manually-add-http-stores?language=en_US

3. Domain pass-through enabled: 

If you are using the domain pass-through auth method, you need to add the store URL to an intranet or trusted zones as mentioned in https://docs.citrix.com/en-us/citrix-workspace-app-for-windows/authentication#modify-the-internet-explorer-settings 

Problem Cause
