Please include this information:

What Grafana version are you using?latest

What datasource are you using?Prometheus

What OS are you running grafana on?linux

What did you do?show the date of prometheus

What was the expected result?The grafana datesource Date&Test should be ok

What happened instead?HTTP Error Bad Gateway

If related to metric query / data viz:

Include raw network request & response: get by opening Chrome Dev Tools (F12, Ctrl+Shift+I on windows, Cmd+Opt+I on Mac), go the network tab.

I install the grafana and the prometheus in kubernetes(version:1.11) pod.I set the prometheus url:http://prometheus:9090 and the Access:proxy,when i exec the grafana Date&Test it shows Success,however when i deployment the node-expoter it shows HTTP Error Bad Gateway and Success.
