Why is Citrix workspace not connecting on macOS Sequoia?

Since the update to Mac OS Sequoia Citrix workspace is not working. Getting a prompt "Citrix Workspace cannot connect to the server. Check your network connection." This is annoying that Apple can't do testing for business applications before a public release. What's the solution?

In my case, the constant Citrix Workspace disconnections appear to have been caused by Sophos Endpoint Security.


Citrix started randomly losing its connection immediately after OSX Sonoma upgraded itself to OSX Sequoia 15.0.1 recently (similar symptoms posted by twojays24). Reinstalling the already-current Citrix Workspace software including removal of its cache and properties files did not fix the issue.

My desktop machine uses a wired ethernet connection which has a fixed IP address, so neither Wifi nor rotating IP addresses were involved. The OSX firewall is active.


The random disconnections stopped immediately after uninstalling the Sophos Endpoint Security software and rebooting the machine.


Next step will be to re-install Sophos and monitor behaviour. I suspect the OSX in-place upgrade didn't play nicely with the Sophos software.
