Forticlient disables the remote app in Mac

[eindaeast]

I'm on an El Capitan 10.11.4 using Forticlient 5.4.0.493. When I turn off Forticlient my remote app (which I use to control a lot of things on my Mac) works. When Forticlient is on, the app won't connect to the Mac. In the previous version I used (5.2.X.X) there were no problems. Has anyone else had this problem? Have you been able to solve it? If so, I'm all ears.

Many thanks for any advice you can supply.

Kind regards
