After upgrading to the new Workspace UI, Citrix Cloud end users are no longer able to access their resources and receive the message "Your apps are not available at this time."

For customers using a proxy to access Citrix Workspace, the following URL must be added to the permitted URLs: https://sf-region.citrixdata.com. If you do not make this change, the new user interface will not load. This URL is the content delivery network (CDN) which hosts the user interface layer for the new Workspace user interface.

If you are unsure where the proxy is located or how to check the current configuration, please contact your network team or system administrator.
