There are a few reasons that an Imunify360™ license may need to be activated manually. For example, the server might already have had a different license for Imunify360. Another example will be transferring the license from a different IP address.
cPanel & WHM™ uses IP-based licenses for Imunify360. After purchasing an Imunify360 license, the following command must be run as root to register the Imunify360 software:
imunify360-agent register IPL
If the imunify360-agent command does not exist, you might need to Install Imunify360™
For additional information regarding how to install Imunify360 manually or use their command-line tools, please refer to the official documentation:
