General Server Error Responses

At any time, the server, may respond with the following status responses in case of error conditions.

• 400 (bad request) If the request is not understood.
• 401 (unauthorised) If the user/pass are incorrect. Or if the server wishes to refuse for another reason.
• 403 (forbidden) If the server rejects the request for a reason other than authentication, such as a network security issue (e.g. IP or MAC is not in an allow list).
• 429 (too many requests) If the client is making requests too frequently, then the server may start rejecting them. This may mean that the client is not obeying the requested polling time.
