Unable to create rendered snapshot

Previously we used to get dashboard snapshot in mail notification. It’s now broken.
I checked logs under /var/log/grafana/grafana.log.
Its showing level=error msg=“Failed to send request to remote rendering service” error=“Get "http://localhost:8082/render/version\”: dial tcp localhost:8082: connect: connection refused"

Ideally what should be the settings under default.ini or grafana.ini in rendering section?

current settings are

server_url = http://localhost:8082/render
callback_url = http://localhost:3000/
#renderer_token = -
concurrent_render_request_limit = 30

Can anyone help me in this?

Hi! It looks like the image rendering service isn’t running. Is it installed as a plugin or run as a separate service?
