The reason I ask this, is as out of 400 tickets I (IT Support) get a month 250 of them are client certificate expiration errors. If we could eliminate this it would be ideal. I don't know why my networks team have not caught wind of it if some solution exists, but I sure want to know. Please please give me an answer, I would very much take this forwards as a change request / possible implementation if there is one. Thanks in advance.
Hi,
Could you please attach the screenshot of the error message that the clients get.
Hello Walter44,
Although your question still requires some more clarification. I am assuming you are asking about SSLVPN authentication using Forticlient but without certificate based authentication. Below are some of the technical documents that you can try but it requires changes in your existing VPN deployment.

Hello
As from the description that client certificate is enabled on fortigate. This error comes when Fortigate ask certififcate from forticlinet.
Please refer this link
