I had tried to setup VPN connection. Using the latest version client and firewall. In windows During the login time it shows

"VPN Server may be unreachable (-14) " . Status shows 80% complete. BUT it works in ANDROID..!!! Anyone resolved this ?

This error also occur if you use the non-fully licensed VPN client, and the SSL VPN configuration on the fortigate firewall has the "Host Check" option enabled. (SSL VPN Portals -> Tunnel Mode -> Host Check)

On the Android client, are you using the same credentials? What type of credentials are you authenticating with? Local, LDAP, etc? I had the same error and it was because a system account we were using for the LDAP authentication was retired and forgot about its usage for authentication.

Check the 'Policy & Objects > IPv4 Policy > SSL-VPN tunnel interface->lan' make sure the user is on the list in the second column.
