Self-Hosted Grafana with Reverse Proxy And Synthetics Plugin

Open yanickflyer opened this issue 8 months ago • 3 comments

What happened: Tried to connect synthetics monitoring with my self-hosted Grafana using the documentation; https://github.com/grafana/synthetic-monitoring-app?tab=readme-ov-file#configuration

But I get the following error: grafana

In the logs I get:

What you expected to happen: The plugin to be installed as below:

How to reproduce it (as minimally and precisely as possible): Access Grafana through a reverse proxy like Traefik, NGINX etc... and you should get the error.

Anything else we need to know?: Managed to make it work with a Reverse Proxy with a workaround

  1. Access Grafana without reverse proxy
  2. Click on Get Started
  3. Access Grafana with Reverse Proxy and it works normally
