Grafana Image rendering

Hello Team,

I am getting this error when trying to use Grafana image rendering.

Error: Failed to send request to remote rendering service logger=rendering renderer=http error=“Get "http://10.59.137.93:8081/render/version\”: dial tcp 10.59.137.93:8081: connect: connection refused

My Grafana server is running on 11003 port number.
Can you please help me on this?
