Alert Collector Fails to Connect to the Specified Manager

Symptom:

During the Alert Collector installation, when I run the Alert Collector status command, the Alert Collector shows the following message:

Unable to connect to the specified manager.

Solution:

When you install the Alert collector on a standalone server that is configured to connect to either the EM or DM, and fails to connect to the manager. The alert collector connects to the manager the first time to determine the manager type (whether EM or DM). When an invalid role is specified, the manager type is used to validate the specified role and switch to the default role.

Verify whether the CAF runs and works on the stand-alone server and the manager. Alert Collector fetches the required info and works properly. This status message is displayed when the manager of the alert collector is changed and alert collector is relaunched. The same steps apply to fix the issue.
