Change agent communication on Linux | Help Center

After installing the DCA and Cloud Connector agent, the communication method can be inserted, changed or removed.

Warning

If the address or port where the Gateway Connector is installed is changed, this information must also be updated in the DCA and Cloud Connector agent to ensure continued communication.

Instructions
