Are there any other logs when pulling the registry? When is your service "WINDEYFOAM-WEB" up? Is it later than the python service? The library will pull the registry every 30 seconds if you are not set the interval time configuration.

eureka_client.init(eureka_server=EUREKA_DEFAULT_ZONE, app_name="WINDEYFOAM-DJANGO", instance_host=INSTANCE_IP, instance_port=SERVER_PORT, ha_strategy=eureka_client.HA_STRATEGY_RANDOM, on_error=on_err, renewal_interval_in_secs=4, duration_in_secs=12, is_coordinating_discovery_server=True ) I set interval 4 seconds. The "WINDEYFOAM-WEB" and "WINDEYFOAM-DJANGO" is up, call back is ok. When I restart "WINDEYFOAM-WEB", "WINDEYFOAM-DJANGO" called "WINDEYFOAM-WEB" failed. the uwsgi config below: [uwsgi] chdir=/usr/src/app module=PythonToolService.wsgi:application master=True socket=/usr/src/app/uwsgi.sock pidfile=/usr/src/app/uwsgi.pid http=0.0.0.0:8093 vacuum=True processes = 4 threads=10 max-requests=5000 enable-threads=true harakiri=120 harakiri-verbose=true
