Kindly remove the forticlient and then check again, by installing it.
Also at what percentage you are facing the issue ?
If the issue still not fixed after re-installing the FCT , then please run the below commands on the FGT and the create the ticket to the TAC with the logs.
diagnose debug reset
diagnose debug application sslvpn -1
diagnose debug application fnbamd -1
diagnose debug enable


Connect the FCT and then observe the logs after that to disable it.
