无法从主机查询领事DNS接口

我能够查询我的远程领事容器的其余服务即。

curl my-ip:8500/v1/catalog/services {"consul":[],"nginx-80":[],"redis":[]} curl my-ip:8500/v1/catalog/service/redis [{"Node":"consul","Address":"172.17.0.3","ServiceID":"954f32f077ed:redis:6379","ServiceName":"redis","ServiceTags":null,"ServiceAddress":"","ServicePort":32768}] 

但是，当我尝试领事的DNS界面

 dig @my-ip -p 8600 redis.service.consul ; <<>> DiG 9.8.3-P1 <<>> @45.33.119.251 -p 8600 redis.service.consul ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached 

我不知道如果我的查询格式不正确，或者我如何启动容器有问题。
