Grafana docker image unable to connect from outside of the host

I was running fine with grafana docker instance for several month. Start from today, I re-deployed with latest image, and I can not connect to the dashboard any more. In docker log, I saw

t=2017-04-01T06:19:45+0000 lvl=info msg=“Request Completed” logger=context userId=0 orgId=0 uname= method=GET path=/ status=302 remote_addr=172.20.0.1 time_ms=0s size=29

and browse give me an error:

Google Chrome’s connection attempt to canaveral-ops.corp.nutanix.com was rejected. The website may be down, or your network may not be properly configured.
ERR_CONNECTION_REFUSED

I wonder why it happens?

The grafana log looks normal and we have no other reports about connectivity errors. Maybe something happened with your docker setup or your networking?

Hi Torkel,

I have a questio, My docker images of grafana is not able to set proxy env. We need proxy to push notification.

I have used below in docker yaml file.
environment:
- GF_SERVER_ROOT_URL=https://ip:port
- GF_SERVER_ROOT_URL=http://ip:port
