Instead of trying to connect to CPs defined in the [CP_LIST] entris of the agent ini file, the agent would only try to connect to the CP listed in the cp= setting.
This can cause problems if the CP the agent is connected to is killed. The agent will remain in a loop trying to reconnect to the same CP rather than going through CP_LIST entries:

Releases 21.0.12 and earlier and 24.3.0 and earlier
This was resolved with the NSK agent on release 24.4.0. Since the agent was updated, the automation engine, utilities, initialdata, and AWI also need to be on 24.4.0 or higher.
