traefik version: 2.2.5 I am working in a managed cloud kubernetes cluster and i have setup consul: Here are the 3 consul servers hashicorp-consul-server-0 1/1 Running 0 30d 10.244.2.12 hashicorp-consul-server-1 1/1 Running 0 30d 10.244.1.13 hashicorp-consul-server-2 1/1 Running 0 30d 10.244.0.10 Here are the services for consul NAME TYPE CLUSTER-IP PORT(S) AGE hashicorp-consul-dns ClusterIP 10.96.112.126 53/TCP,53/UDP hashicorp-consul-server ClusterIP None 8500/TCP,8301/TCP,8301/UDP,8302/TCP,8302/UDP,8300/TCP,8600/TCP,8600/UDP hashicorp-consul-ui ClusterIP 10.96.199.36 80/TCP On my traefik ingress controller, I have enabled these consul provider configurations as per traefik's consul documentation ([https://docs.traefik.io/providers/consul-catalog/](https://docs.traefik.io/providers/consul-catalog/)) : - "--providers.consulcatalog=true" - "--providers.consulcatalog.prefix=traefik" - "--providers.consulcatalog.endpoint.address=http:// 127.0.0.1:8500" When i deployed traefik and looked at the logs, I am getting Get "[http://127.0.0.1:8500/v1/catalog/services](http://127.0.0.1:8500/v1/catalog/services)": dial tcp 127.0.0.1:8500: connect: connection refused" providerName=consulcatalog Provider connection error Get "[http://127.0.0.1:8500/v1/catalog/services](http://127.0.0.1:8500/v1/catalog/services)": dial tcp 127.0.0.1:8500: connect: connection refused, retrying in 535.639805ms" When i tried to connect to one of my servers like - "--providers.consulcatalog.endpoint.address=http://10.244.2.12 :8500", it had no errors Interestingly, when i tried [http://hashicorp-consul-server:8500](http://hashicorp-consul-server:8500) and use a curl witihn one of consul server, the curl works, but when i used - "--providers.consulcatalog.endpoint.address=http://hashicorp-consul-server:8500" time="2020-08-07T19:45:23Z" level=error msg="error get consul catalog data, Get "[http://hashicorp-consul-server:8500/v1/catalog/services](http://hashicorp-consul-server:8500/v1/catalog/services)": dial tcp: lookup hashicorp-consul-server on 10.96.5.5:53: no such host" providerName=consulcatalog time="2020-08-07T19:45:23Z" level=error msg="Provider connection error Get "[http://hashicorp-consul-server:8500/v1/catalog/services](http://hashicorp-consul-server:8500/v1/catalog/services)": dial tcp: lookup hashicorp-consul-server on 10.96.5.5:53: no su ch host, retrying in 406.49185ms" providerName=consulcatalog that 10.96.5.5:53 is from the kube dns. Is there a way to use one ip address or domain which can route to all 3 consul servers? Thank you. Hoping to hear an answer 🙂 ---

note that i have tried "--providers.consulcatalog.endpoint.address=http://hashicorp-consul-server..svc.cluster.local:8500" and i do not have any errors on consul connection. Any other solutions are welcome too.
