Snapshot image creation fails. PhantomJS QNetworkReply::NetworkError

khallela · August 27, 2019, 6:17am

I am running Grafana v6.3.3 (commit: 84d0a71) via the official grafana/grafana:6.3.3 Docker image. It includes PhantomJS version 2.1.1.

I tried this with grafana/grafana:6.2.0 as well, and had similar results.

I have Grafana configured with an S3 bucket as the external snapshot storage, but I have tried this with local as well.

When I visit a dashboard and try to generate a snapshot, I get the “Grafana / Server Error” page with a message that says “Rendering failed.”

I see something like this in the Grafana logs:

When I enter the Grafana container and execute the PhantomJS command shown above with debug=true, I get something like this:
