2. In the error log, there is "Send failed: unknown error (-1)". Check the terminal firewall and confirm that the firewall is enabled.

3. After closing the firewall, wait a few minutes for the agent to come online normally (Note: Closing the firewall needs to be agreed upon with the customer. If it is inconvenient to close, you can also solve it by allowing the ipc_proxy.exe process through the firewall policy).
   

   Solution

   Turn off the firewall or configure the firewall policy separately to allow resolution.
