Within the last few days one of our users forticlient VPN has been failing to connect and comes up with the below error

"VPN connection failed. Please check your configuration, network connection and pre-shared key then retry your connection."

Nothing has changed with his broadband connection and it has all work previously

Steps i have done so far

Uninstalled and reinstalled Forticlient with latest version → same error
deleted the VPN profile and re-created → same error
tested with personal logins → same error
setup different VPN profile and tested → same error
tested user login details on 2 other computers in different locations both times logged in → not a username/password problem
rebooted laptop → same error
Checked TSL settings 1.1 and 1.2 are ticked - same error
added Forticlient to firewall to allow through - same error
checked if any spaces had been added when copying pre-shared key, gateway and local ID details → there where none

I am pretty much running out of ideas as what else could be the problem. Any suggestions would be great

Thanks

I've had a similar problem that affects one user. Have you tried to change the password for the user?

Please check your forticlient advance configuration, DH configuration and firewall configuration same it's correct or not. I am also facing same issue with my client. I did same process and it has been resolved.
