Block IP Address on FortiGate's Firewall Failing

Hi everyone,

I'm having an issue where I setup a rule to block an IP address using the Block Active Response on SW LEM:

Using the Block IP Active Response - SolarWinds Worldwide, LLC. Help and Support

The rule fires, we get a pop-up message on the machine that receiving the effect of the rule, but the rule's operation

fails and shows the following error message on SW LEM:

See attachment.

I checked my credentials (they have read-write access), I did a SSH connection to the FortiGate (FGT) and it was

successful, I changed the SSH port, I unrestricted the SSH on the appliance, etc.

NOTHING.

Any help is appreciated.

Thanks!
