Image Rendering Failed

[antonio]

Hello @zeusnet and everybody else

This seems to be related to a known issue which was reported in this post that also contains a solution:

Failed image rendering - Unauthorized request

I had a similar issue and upgraded both Grafana and Grafana Image Renderer to latest versions. This fixed the issue. Take a look at this: Security release: New versions of Grafana and Grafana Image Renderer with a high severity security fix for CVE-2022-31176 | Grafana Labs

Hope it helps
