Prometheus unable to connect to server (Connection Refused error)

[Krishna Yada]

Hello Team,

Am unable to start the prometheus, Installed properly followed this document.

https://www.digitalocean.com/community/tutorials/how-to-install-prometheus-using-docker-on-centos-7#step-2-setting-up-node-exporter.

Each and every step I followed, but I am not getting where I made the mistake. 

cAdvisor is also running fine on the same server, 

when I try to run Prometheus, it refuses to connect to the server.

Please advise.

Thanks

Krishna
