Connection was terminated unexpectedly error 104
Fortigate 60C running 5.2.13
FortiClient 184.108.40.206 on Mac 10.13.6
My user clicks the FortiClient icon in the menubar, Connect to VPN, enters her credentials, and clicks Connect. Then, it tries to connect for several seconds before the error in the title pops up. Her internet connection is working otherwise. Any tips or recommendations to troubleshoot or workaround this issue?
