Hello, Did you try to reset Wem Cache on your VDA ? You can use a Script : net stop "Citrix WEM Agent Host Service" /y del /f "C:\Program Files (x86)\Citrix\Workspace Environment Management Agent\Local Databases\*.db" net start "Citrix WEM Agent Host Service "c:\Program Files (x86)\Citrix\Workspace Environment Management Agent\AgentCacheUtility.exe" -refreshcache pause

The VDA was a complete new build that installed WEM 2311, wasn’t an upgrade to 2311. Did test a cache refresh anyway but same issue

Maybe a bug in these version ? I think it's necessary to open a citrix case. For years I had some similar problems with WEM 2203 and these version had a bug which was fixed in 2206.

Found that running AgentCacheUtility.exe -refreshcache -reinitialize resolved the issue but this was a fresh VDA build and checks into WEM successfully. Case logged anyway
