Image Rendering Failed

Grafana Dashboards
1

I’m still trying to work through this issue, Discord alert graph image is wrong.
I have installed grafana-image-render and all its dependencies, but am now seeing a new issue. I get a straight up error when trying to render images.
I’m currently getting this error now: https://i.imgur.com/s3e7E8w.png

I’m using SSL, root url set as, https://ops.site.net/stats. Domain set as, ops.site.net.

Hi mates,
I’m facing same issue. My grafana app is hosted in private network with “development” hostname.
I have certificate for publik dns record, which makes my grafana available outside private network. The problem is that do not have ablity include production hostname into cetificate.
Am I able change security levels or something like for render plugin?
