HTTP 206 Partial Content vs 502 Bad Gateway

HTTP 206 (Partial Content) is a 2xx Success response, while 502 (Bad Gateway) is a 5xx Server Error response. 206 indicates that the server is delivering only part of the resource due to a Range header sent by the client. Used for resumable downloads and video streaming. In contrast, 502 means that the server, acting as a gateway or proxy, received an invalid response from the upstream server.
