API key + node red request = 404 error

Trying to get list of devices usign node red, providing correct api key, but got 404 error, where could be an issue ?

Thank you

404 means that the URL you are calling does not exist.
Many things can explain that. Maybe you are trying to access to the REST API proxy on the wrong port (default port is 8090), or maybe the proxy is not running correctly.
See: GitHub - chirpstack/chirpstack-rest-api: ChirpStack gRPC API to REST proxy.
