Grafana Rendering Plugin not working for slack

Unfortunately the rendering plugin for Grafana does not work.

In Pushover this is displayed correctly as well as in the test, but as soon as a correct error message comes, nothing is uploaded.

Attached are the logs: Hastebin: Send and Save Text or Code Snippets for Free | Toptal®

Does anyone have an idea? I have generated the whole thing via WebHook and in the test it runs without problems.

I found the following error, unfortunately I can’t get any further:

ploading to slack via file.upload API" logger=alerting.notifier.slack

welcome to the :grafana: community @mesosource!

If it’s working in test, but not when a real event happens, it might be timing out. I can’t see your logs, did they have debug logging enabled?

If you go to the dashboard that generated the alert and click the share icon

Do you use grafana in HTTPS mode ? I notice similar issue, but with mail announcements here.
