Troubleshooting agent registration

Review the following information that is related to troubleshooting agent registration issues.

On Windows, if the agent fails to establish a connection with the PowerProtect Data Manager server, agent registration might fail with the following error message:

During a network connectivity test, the agent is unable to reach the PowerProtect Data Manager server by using ping. 

1.	If the ping command is blocked in the environment, the agent registration can still complete successfully. 
Review the agent service logs at INSTALL_DIR\DPSAPPS\AgentService\logs to verify that the registration is successful. If the registration is successful, the status of the agent host indicates Registered in the PowerProtect Data Manager UI.
2.	If the ping command is not blocked in the environment, the agent registration might not complete successfully because a network connection cannot be started. If this occurs, complete the following steps to troubleshoot the issue:

On Linux or AIX, if the agent fails to establish a connection with the PowerProtect Data Manager server, agent registration might fail with the following error message:

During a network connectivity test, the agent is unable to reach the PowerProtect Data Manager server by using ping and curl. 

1.	If the ping command is blocked in the environment and curl is not installed, the agent registration can still complete successfully. 
Review the agent service logs at /opt/dpsapps/agentsvc/logs to verify that the registration is successful. If the registration is successful, the status of the agent host indicates Registered in the PowerProtect Data Manager UI.

If agent registration fails with these error messages, complete the following operation:

  1. Use any network packet tracing tool to trace the packets from the agent system to PowerProtect Data Manager.
  2. Start the packet tracing between the source IP of the agent system and the destination IP of PowerProtect Data Manager.
  3. Start the network traffic between the agent system and PowerProtect Data Manager.

    Wait 10 to 15 seconds.

  4. Analyze the captured packets.
  5. Look for SYN and SYN_ACK packets to see if a 3-way handshake is being performed.

    Determine whether the source agent or the destination PowerProtect Data Manager is blocking the connection.

    If network traffic is blocked, contact your network security team to resolve the port communication issue.
