httpsd process is missing

Hi,

Please take a look at https://community.fortinet.com/t5/FortiGate/Technical-Tip-GUI-is-not-reachable-after-an-upgrade/ta-p/192936

Check if the HTTPSD shows up using the following command:     fnsysctl ls /var/run/  fnsysctl cat /var/run/https.pid     If HTTPSD does not show up, run a sniffer on FortiGate. FortiGate is responding with RST to the HTTPS request. diag sniffer packet any "host <IP address>" 4 0 l IP address: Source PC ip address from where user trying to access FortiGate GUI.  Check if there is an admin-server-cert configured: config system global show full | grep server-cert  If it is not configured, configure it as follows: config sys global      set admin-server-cert Fortinet_Factory end  After this, try accessing FortiGate via the GUI again and it should work.
