i'am using here FortiOS 6.2.4 with deepinspection in Flow and Proxy based mode. A few weeks ago the great event was where there were problems with wrong or broken SSL certificates. Since then I have had problems with websites again and again.
For example "logoix.com". If i call the site i get an proxy error in flowbased mode. In proxybased mode i get an error with an invalid ssl certificate. And there are a lot of site more. Normal sides, trusted sites.
So if i check the box "Allow Invalid SSL Certificates" all websites work as usual. So what does it really mean? Becaues if i have a look at the certificate in the webbrowser, it look like ok.
