Same problem here, my environment:

Platform: Azure
Deployment: acs-engine

Versions:

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.2", GitCommit:"81753b10df112992bf51bbc2c2f85208aad78335", GitTreeState:"clean", BuildDate:"2018-05-12T04:12:12Z", GoVersion:"go1.9.6", Compiler:"gc", Platform:"darwin/amd64"}

Steps to reproduce
Successfully installed Kubernetes 1.10.2 using acs-engine on Azure:

$ kubectl cluster-info
Kubernetes master is running at https://<REDACTED>.cloudapp.azure.com
KubeDNS is running at https://<REDACTED>.cloudapp.azure.com/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
kubernetes-dashboard is running at https://<REDACTED>.cloudapp.azure.com/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy

Followed steps under https://github.com/kubernetes/dashboard/blob/master/README.md:
Run

$ kubectl proxy

Then opened this url on my browser http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

Observed result

Error: 'dial tcp 10.244.0.9:8443: getsockopt: connection timed out'

same problem here with kubernetes v1.10.3, dashboard v1.8.3.

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
outputs:

Error: 'net/http: TLS handshake timeout'
Trying to reach: 'https://10.244.1.144:8443/'

but if changed it to
http://localhost:8001/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/, it shows:

Error: 'net/http: HTTP/1.x transport connection broken: malformed HTTP response "\x15\x03\x01\x00\x02\x02"'
Trying to reach: 'http://10.244.1.144:8443/'

So the service must be normal.

any update on this issue?

[dennis-xie]

master install flannel

I am experiencing the same issue with Kubernetes 1.10.4

[tubzby]

Finally reinstall recommended docker version 17.03 fixed my problem.

[aar6ncai]

[leeadh]

same problem, how do we resolve?

[maciaszczykm]

Unfortunately you have to wait for the next release when we will introduce changes allowing to use it with Kubernetes 1.10.

kubectl --namespace=kube-system port-forward kubernetes-dashboard-5bd6f767c7-8bhkf 8443

https://127.0.0.1:8443/
