502 bad Gateway

rlinux57 · February 13, 2019, 7:42pm

Hi Team,

I have installed latest version of grafana-5.4.2 and integrated with nagios core using PNP datasource. I am getting following error 502 bad gateway while adding pnp datasource. Please help me in order to resolve this issue.
I already use the same setup on other server and it’s working fine.

Hi,

I have sorted out the issue by myself by adding URL entry for localhost in /etc/hosts file.
