Description
This article describes how to troubleshoot an issue when receiving a response code 400 error upon uploading the license.
Scope
FortiGate.
Solution
If the error message 'Invalid license file' is received after uploading the correct VM license file.
For example error on update debug logs:
2021-08-05 12:38:32 upd_pkg_verify_setup_rsp[1115]-Unexpected setup rsp code 400
2021-08-05 12:38:32 upd_act_setup_with_action[220]-Received invalid setup rsp
config system fortiguard
set fortiguard-anycast disable
end
If it does not work with the configuration above, try enabling the protocol UDP:
config system fortiguard
set protocol udp
end
config sys global
get | grep auth-cert
auth-cert: Fortinet_Factory
execute ping service.fortiguard.net
execute ping update.fortiguard.net
execute ping guard.fortinet.net
execute ping fds1.fortinet.com
execute ping directregistration.fortinet.com
Allow up to 4 hours for the changes to take effect, then check whether the license status has updated to valid.
If these steps do not resolve the issue, collect the debug logs along with the output of the commands below and provide them to the FortiGate technical support team:
diagnose debug disable
diagnose debug reset
diagnose debug application update -1
diagnose debug enable
execute update-now
Wait for 2-3 minutes before stopping the debugs:
diagnose debug disable
diagnose debug reset
