Description
This article describes how to update SSH timeout if Telnet server debug log errors as 'Failed to get operation result within specified timeout:' is appearing.  
It Will also help if there is network congestion and requests/replies are taking time to occur.

Solution
For FortiNAC 8.8.x.

Go to System -> Settings.





Select 'Network Device' and then change the Telnet/SSH Connection Timeout (Sec).




Start with 30 seconds and increase in 30 second increments until to get a work duration.

For FortiNAC 9.1.x or higher (This assumes that the settings are in the default locations. Otherwise, it will be the same as 8.8.x).

Go to Network -> Settings -> Network Device.





Start with 30 seconds and do 30 seconds increments until to get a working interval.
