I'm facing a very strange issue. I'm running FortiOS 7.0.8. On some of my FortiGate, I can't access to web gui trough LAN interface. On my browser, I can see the certificate warning and after I accept it, the donut is running indefinitely.
If a do a packet capture during this, I can see paquet transiting trough my FortiGate to web interface port.
If i go trough wan interface, I can access to the login page without any problem and suddenly, I can access to web gui trough lan for a while...
Very very strange no ? Someone can help me to understand what appends ?
