Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
‘HTTP error’ message
Request URL: https://avikchatterji.grafana.net/api/datasources/proxy/38/api/v2/services
HTTP 502


“localhost” means “this machine” (whichever machine it’s used on), so unless
you’re running Zipkin on the machine that’s running Grafana, that won’t work.

You’ll need to give the Grafana server a hostname or an IP address where it
can access the Zipkin service.

Antony.

Still getting HTTP error in Grafana after giving the below detail. But able to open Zipkin from the browser
