Hi, i have this problem. I didnt have this problem when i was at my old notebook. I am trying to reach my University VPN - but i have error - i reach 10% and it write Unable to establish VPN connection. The VPN server may be unreachable. I tried to solve this but i dont know what to do anymore.

I also noticed that i cannot ping server that i want to connect to

The weird thing is - i once was able to connect - so i thought it is solved...

    If the FortiClient stops at 10%, the issue is usually related to local Network/PC related issue

    Follow the below checks

    -Make sure the correct remote gateway is set on the FortiClient settings

    -Make sure the correct port number is being used for sslvpn connection

    -Check if the firewall is enabled on the pc where forticlient is installed, which could be causing an issue

    -Once these checks are done also check the network.
