After upgrading to macOS 27, I encountered an interesting issue with Citrix Workspace App.
After entering the store URL, the following error appears:
The URL specified in the provisioning file cannot be contacted.
The initial suspects are, of course:
– StoreFront
– NetScaler
– DNS
– Firewall
– Certificates
In this case, however, the cause lay somewhere completely different.
Cause
Under
System Settings → Privacy & Security → Local Network
, the entry ServiceRecords was disabled.
After enabling the permission, sign-in immediately worked again.
✅ The store could be added
✅ Username and password were accepted
✅ Workspace App worked normally again
Why this is interesting
The error message suggests a network or StoreFront problem.
In reality, macOS blocks Workspace App’s local network communication, causing discovery to fail.
Especially after upgrading to macOS 27, it is worth checking privacy settings before starting to:
– Analyze StoreFront
– Check NetScaler
– Replace certificates
– Capture network traces
Sometimes the cause is much closer than expected.
Has anyone else observed this behavior after upgrading to macOS 27?
