Start with nacos/client.py, especially get_server_from_url and the urlopen call using ADDRESS_SERVER_TIMEOUT. Reproduce the intermittent timeout and inspect the complete server-address configuration and traceback. Done means the cause is identified and the SDK handles or reports this failure consistently.
