Citrix StoreFront Error “Cannot complete your request”

While replacing Citrix StoreFront (2203 CU5 LTSR) servers running Microsoft Server 2019 with servers running Server 2022, we encountered an error message during login attempts to Citrix StoreFront. Users were shown an error message stating: “Cannot complete your request.”

We were running a GSLB setup with a multi-server group (across sites), each containing several Citrix StoreFront servers (2203 CU5 LTSR). As described in “Virtual Apps and Desktops – 1912/2203 – Citrix Infrastructure / OS Upgrade” (CTX278869), we exported the configuration from an old StoreFront server running Server 2019 and imported it onto the newly created StoreFront servers running Server 2022. All servers were deployed in the same OU, received the same GPOs/settings, and apart from the different operating systems, all settings were pretty much identical.
