HTTP 203 Non-Authoritative Information vs 406 Not Acceptable

HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 406 (Not Acceptable) is a 4xx Client Error response. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. In contrast, 406 means that the server cannot produce a response matching the Accept headers sent by the client.
