I can access kibana UI if I for port forwarding with kubectl -n kube-logging port-forward svc/kibana 5601:5601

There isn't any error on Traefik dashboard.
Whats is wrong with my setup here ?

Hello @rp346

According to the attached logs Traefik can't reach Kibana running on 5601 and gets a connection refused. Can you please validate whether Kibana endpoint is reachable - kubectl get endpoints ?

3

Here is the output of endpoints

% kubectl -n kube-logging get endpoints -l app=kibana
NAME     ENDPOINTS          AGE
kibana   10.100.5.33:5601   5m45s

and error from Traefik

time="2021-05-26T14:35:10Z" level=debug msg="'502 Bad Gateway' caused by: dial tcp 10.100.5.33:5601: connect: connection refused"

But port forwarding works perfectly & can access kibana on http://localhost:5601/

% kubectl -n kube-logging port-forward svc/kibana 5601:5601
Forwarding from 127.0.0.1:5601 -> 5601
Forwarding from [::1]:5601 -> 5601

Also able to telnet from same namespace as kibana

$ telnet kibana 5601
Trying 172.20.117.213...
Connected to kibana.kube-logging.svc.cluster.local.
Escape character is '^]'.

I would try to run a temporary pod in the same namespace where you have Traefik deployed and tried to reach Kibana through curl command.

Here is exactly the link how you can test it: https://youtu.be/CL5Cxxz-yHo?t=1532

Any updates? I have the same issue.

Update: The problem is that Kibana is listening particular interface.
Solution is to setting server.host: 0.0.0.0 property for Kibana
