I can't access to my firewall Fortigate 201E with web administration

Let me submit one issue ...

In my network, I have two FortiGate 201E firewalls (both are same model but different serial numbers) ...one is use for production (it is with licensed) and another FortiGate 201E is no use (just for backup purposed and licensed expired). I have taken configuration from production one and try to put in my backup firewall (backup config is put to backup firewall). 

After config received and rebooted the backup firewall, it can't access with web access (normally we have access with https://(firewall iP:44443)) but I can access with SSH. I can see https, ping, ssh, are allowed access from backup firewall's management interface.  So, is there any issue? It is related to licensed expired on backup firewall. 

If anyone got same issue..., could you please suggest to me for how to. Thank you.
