Agent does not reconnect after service restoration if both DNS and Wazuh fail

[mmccarn]

4.9.0-1	wazuh-agent	Agent	Packages	macOS 15.0.1
4.9.0-1	wazuh-agent	Agent	Packages	Ubuntu 22.04.5 LTS

4.9.0-1	wazuh-agent	Agent	Packages	Microsoft Windows 10 Pro 10.0.19045.5011

Relevant Configuration Details

• All-in-one Wazuh server (proxmox guest)
• Local DNS (proxmox guest, same node as Wazuh server)
• Agents configured to connect to Wazuh using DNS hostname

Incident Details

• proxmox node failed
• proxmox node rebooted
• wazuh operation restored
• physical agents, and agents from other nodes, did not reconnect
• agents remained disconnected for over 24 hours
• agents reconnected successfully using .../bin/wazuh-control restart

Questions

• Should disconnected agents reset themselves periodically?
  • Is there a configuration option to enable this behavior, or a scheduled task I can create?
• If this is something that deserves developer time, are there logs I should provide?

[edit - add Windows guest and correct spelling]
