Hi, I am using Grafana v9.1.7.I was trying to create alert in our organisation teams channel using incoming webhook. But when I configure the webhook url in the grafana and try to send a test alert the test alert fails.
Can you determine if your MS Teams webhook works from another application (besides Grafana)? The error message shown ends with “connection refused” so I am thinking there is something (firewall setting, etc.) that is not allowing your webhook to go through.
Good to know. I also struggled with a similar webhook issue where the device receiving the webhook would not permit it due to some sort of HTTP security block. My workaround was to send the webhook to Node-RED running on the same server that is runnning Grafana, then transmit the message via MQTT to the other device (which was blocking the webhook).
