Description
This article describes restoring the FortiGate configuration from GUI, the FortiGate is sometimes inaccessible via HTTP or HTTPS.
However, SSH or Telnet access to the FortiGate unit is still possible.
Scope
FortiGate.
Solution
The admin server certificate can not have been selected because HTTP/HTTPS access is not working.
As of now, the HTTP/HTTPS access is not available, 2 options are possible to proceed with.
- Console connection: Connect the computer directly to the console port using RJ45 to db9 cable or RJ45 to USB cable.
- SSH access: Using Putty, put the IP of the FortiGate along with the port number.
After the above steps select open and log in using the admin username and password.
To correct this behavior, use the following CLI commands to set the certificate to self-sign.
config system global
set admin-server-cert {self-sign | Fortinet_Factory | <certificate>}
end
Once the server certificate is set, open the browser and try to access the FortiGate with its IP and port number.
