Failed to send request to remote rendering service

Hi Guys please let me know if you can help me with this error. I am running Grafana v7.0.1 on a ubuntu server and is great the only issue I have is with the images on the notifications of if I try to create a Direct link rendered image. the emails notification do not include the image and if I try to create a direct link rendered I get an errror.

If I check the /var/logs/grafana/grafana.log I get this. I did install the plugin using this command
sudo grafana-cli plugins install grafana-image-renderer

error="Failed to send request to remote rendering service.

Good afternoon. I’m having the same problems. version 7.0.3 only

Does “netstat -lptn” confirm that you have anything listening on localhost port
8081?
