Question

'Credential or SSLVPN configuration is wrong" / Fortinet SSL VPN Virtual Ethernet Adapter missing

  • December 11, 2024

Good afternoon,

I have just upgraded some of the company computers to FortiClient VPN 7.4.1.1736.

We use SAML authentication to log in.

 

On 90% of them everything seems fine, but on the remaining 10% they always get 'Credential or SSLVPN configuration is wrong. (-7200)'.

 

I have tried to log in to the VPN on the affected machines and I get the same problem.

 

On my machine, everything works fine, I have the same configuration as I deployed through Intune, and the affected machine's primary user can connect to the VPN from my machine.

 

So it doesn't seem to be a problem with the credentials or the SSL configuration.

 

One thing that seems strange to me is that the Fortinet SSL VPN Virtual Ethernet Adapter is missing from their network adapters. Despite our attempts to reinstall the Forticlient, the adapter won't appear. Could this be the problem? How can we solve this?

 

Here are the few logs I was able to get from the client:

Hello,
I was able to reproduce the issue, using on the affected computer.
