Issues with FortiGate Firewall

We are an ITC that uses a FortiGate NGF. We are having many issues with reaching most sites since the cert has been expired. I am wondering if there is anything specific to our FortiGate that we can do to solve these issues.

Thank you in advance for any help!

Same problem here. It seems related to the R3 expired intermediate authority. The SSL inspection is not able to validate chains.

Me too!!!
I've more than 50 customer with ssl insection on... Need to disable on all of them!!!!

Please report this to Fortigate: the more customers complain about this issue, the sooner Fortigate develops a fix.
