FortiClient on Student Macs

Has anyone seen an issue before where a user will bring their Macbook home and the Forticlient will not let them open any Applications. I'm having multiple students come to me saying they are receiving the following error messages when they bring their Macbooks home. It keeps popping up like as the Application wants to load but it can't. As soon as they come back into the school, the error might pop up for a bit but then it starts loading Applications. It seems to happen when students break their connection (the laptop shuts down, they join another wlan).

What bothers me the most is it sorts itself out about a week later.

Students are using v5.4.1
