Technical Tip: FortiBalancer error message "Someone else is in config mode. Access denied!"

[adebeer_FTNT]

Description

Under certain circumstances, it can happen that an admin user was in config mode, and the session was not terminated correctly.

Later, when an admin user wants to enter the config terminal mode, the following message is displayed:

FBL-1#con t
Someone else is in config mode.
Access denied!
Command failed: error code -1.

Scope


Solution
To force the disconnect of the previous user session from the config mode, use the CLI command:

FBL-1#config terminal force
FBL-1(config)#

This command should allow the admin user to enter the config terminal mode, where it would be possible to proceed with further configuration steps.
