Question

Cert error when connecting over cable to Office 365

Hi guys,

We are having an issue when ever someone connects via cable. A certificate error keeps popping up when connecting with ethernet. This does not happen over the WiFi. This has always been an issue. Nothing has changed. I have ensured that no cert inspection is enabled on the firewall. I have tried changed the system certificates and done a lot of research. This error is only applicable when trying to connect to Office 365.

Any insight ?

    When the certificate pops up is it issued by fortinet? Use IE and click on the pad lock next to the address bar.

    There must an ssl/ssh inspection profile enabled on your policies if you are seeing that. Running a #diagnose debug flow. With some filters for your src ip will show you which policy I'd you are hitting.
