I get an error in the log saying: time="..." level=error msg="integration/http: publish event error" ctx_id=<> dev_eui=<> error="expected 2XX response, got: 400" event_type=up url="https://<>.es.io:9243/index/_doc/?event=up"
The chirpstack webui does provide a valid let’s encrypt certificate.
When I change the URL to a Postman mock server I receive it successfully.
What could be the reason for this?
Thanks for your support.
The error indicates that your endpoint returned a 400 status, but a 2XX status is expected. You should inspect why your endpoint is returning a 400 status.
