VPN connection failed. Please check your configuration, network connection and pre-shared key then retry your connection. If the problem persists, contact your network administrator for help.

This error appeared in the FortiEMS and not in the basic FortiClient VPN version.

If the above error screen appeared, there is three reason to sort outs:

• Account locked in the domain environment.
• Password expired.
• Account expired.

If the password expire and you already change to the new password and still appeared the above screen there might be synchronization issue and wait for the completion of synchronization time.

If your organization use the direct firewall authentication instead of AD there might be littlie bit delay to sort that issue due to AD need to communicate the Firewall.
