Technical Note: FortiManager is unable to retrieve configuration 'Failed to reload configuration. Duplicate'

[cfirpo_FTNT]

Description
Importing FortiGate configuration fails with the following message: "Failed to reload configuration. Duplicate"
Solution
To correct the issue run the following commands on the FortiManager to identify the device OID and detect the duplicates.

Note: Log the CLI SSH session to a file

To identify the FortiGate OID:

# diagnose dvm device list

Then attempt to reload the configuration

#diag test deploymanager reloadconf 429829

 The ssh session will close look at the output file:

Retrieving configuration file from FGT...
Configuration file import succeeded.
Reloading configuration file...
Error: Configuration reload error.

Go into the FortiGate and delete the duplicates from the web filter profile.

Repeat the process until there are no more duplicates detected.

Finally, retrieve the configuration.
