SSL VPN is not able to connect gets stuck at 10%

Hi Sushil,

Thank you for posting to the Fortinet Community Forum.

As per your problem description I can understand that you are facing issue while connecting to SSL VPN and it is getting disconnected at 10%.

Please check below steps:-

> Check whether you are able to telnet the ssl vpn server IP on the ssl vpn port
> Checked internet connectivity from the pc end
> Check whether ssl vpn configuration in forticlient has been correct
> Check whether the external public IP has been deny by firewall local in policy
> Check whether server certificate has been selected in ssl vpn settings in FGT
