I have seen the error message "The VPN client agent was unable to create the interprocess communication depot" linked to Windows installs and Internet Connection Sharing turned on. I have AnyConnect version 4.8.01090 installed on a late 2014 Mac mini running macOS 10.15.1 (Catalina) and that error message started appearing in an alert after enabling AnyConnect. I have nothing similar to "Internet Connection Sharing" turned on on the Mac.
The problem initially appeared with 4.8.00175 running. I had moved:
- /Library/LaunchAgents/com.cisco.anyconnect.vpnagent.plist
- /Library/LaunchDaemons/com.cisco.anyconnect.gui.plist
to the desktop to try to prevent the UI from starting even when the VPN service was not needed. This prevented the service from starting. I moved:
- /Library/LaunchAgents/com.cisco.anyconnect.vpnagent.plist
back, and the VPN service worked, but the error messages started. I ran "Uninstall AnyConnec.app" to uninstall 4.8.00175, rebooted and re-installed 4.8.00175, but the error messages continued. When 4.8.01090 came out, in uninstalled 00175, rebooted and installed 01090. Before the installer completed, the error messages returned.
Any ideas/suggestions?
