Receiving error when connecting to Citrix Receiver for external use.
I am more of Citrix person, than F5, but we are trying to deploy Citrix Receiver to all domain based endpoints. We are using Xendesktop 7.6 and StoreFront 2.6.0.5031 with a single FQDN Certificate. Internally works fine using Receiver for Web and Citrix Receiver GUI - SSO. However externally won't work correctly with Citrix Receiver, but works fine with Receiver for the Web with Pass-through. We have an F5 and are using the latest iApp. We are using the icaclient ADM Template for all domain based machines and have setup Storefront Account to https://storefront.company.com/Citrix/Store/discovery;on;Description (example). We enabled pass-through authentication = Enabled, Allow pass-through authentication for all ICA connections = Enabled in the GPO.
The error we receive in Citrix Receiver when trying to refresh apps externally is "Your apps are not available at this time. Please try again in a few minutes or contact your help desk with this information. Cannot contact (store). It appears its not communicating back to the F5 at all. Citrix mentions its something not configured correctly on the F5 and they can't support it. I am curious if anyone else has run into the issue and how to fix? Let me know if you need more information.
Thanks!
