Start with consumer/proxy/ProxyFactory.php around lines 213 and 225, then trace the calls from api/FSOFApi.php and demo/demo-consumer/server/Consumer.php. Check how provider information is read from Redis for com.fenqile.example.DemoService and compare it with the consumer configuration. Done means identifying why no provider is found and documenting or correcting the cause.
