Description This article describes the issue with assigning FortiToken to a user and steps to verify if 'Timeout occurred! No data rcvd after 240 seconds' occurs in FortiToken debug.

Solution

While assigning FortiToken to Users, 'Some unknown error!' appears.

To resolve the issue of being unable to assign FortiToken to users, follow these steps:

 

Step 1:

Check the FortiGate configuration and ensure that the FortiToken is properly configured and licensed.

 

Step 2:

Verify the reachability to the  DNS server. If DNS is unreachable, refer to the steps in the article Technical Tip: How to solve 'unreachable' or high latency issue when using FortiGuard DNS servers.

 

Step 3:

Verify and ensure the reachability to FortiGuard and these servers:

 

exec ping fds1.fortinet.com
exec ping directregistration.fortinet.com
show system central-management

 

Step 4:

Collect FortiToken Debug logs:

 

diagnose debug dis
diagnose debug reset
diagnose debug console time en
diagnose debug app forticldd 255
diagnose fortitoken debug enable
diagnose debug enable
diagnose debug info
 
To Stop Debugging:
 
diagnose debug disable
diagnose debug reset
 
If the following error is received:

Try adjusting the MTU value of the WAN interface, as described in the article Technical Tip: How to adjust the Maximum Transmission Unit (MTU).

 

config system interface
    edit "<wan_interface>"
        set vdom "root"
        set mtu-override enable
        set mtu 1300
    next
end

 

If the issue persists, collect debug logs and contact FortiGate support for further assistance.
