Troubleshooting Tip: Issues in FortiGate GUI: Pages Failing to Load Completely

1. Identify the Issue with the Fortinet Support Tool:

• Ask the client to use the Fortinet Support Tool Google Chrome extension, which can collect debug information for troubleshooting GUI issues.
• Instruct the client to access the problematic pages using the GUI while the tool captures logs. The captured data will help identify errors: Technical Tip: Fortinet Support Tool - Google Chrome Extension for troubleshooting GUI issues

The interface menu just keeps loading:

SD-WAN members just keep loading without displaying any information:

The LDAP server just keeps loading.

2. Resolution via GUI:
   • Navigate to System -> Settings -> System Time in the FortiGate GUI.
   • Check if the configured timezone has the zoneinfo prefix (e.g., zoneinfo/Mexico/BajaSur).
   • Update the timezone to a valid entry without the zoneinfo prefix (e.g., zoneinfo/Mexico/BajaSur).
   • Save the changes.

To configure the date and time in the CLI:
Configure the timezone and daylight savings time:

config system global
    set timezone <integer>
    set dst {enable | disable}

end

To view which timezone has which integer assigned to it, press 'shift+?' after entering the command 'set timezone' on the CLI. It will give the whole list of all timezone entries with integer assigend to it.  

To manually configure the date and time:

Manual:

execute date <yyyy-mm-dd>
execute time <hh:mm:ss>

3. Log Out and Log Back In: After making the changes, log out of the FortiGate GUI and log back in to ensure the changes are properly applied and errors do not persist in the session.
