All:

I am successfully able to browse an MP3 website and play the MP3 streams without issue through Nginx (1.19.2).

However, when attempting to download an MP3 through Nginx, I'm receiving a 206 Partial Content HTTP Response:

192.168.0.154 - - [07/Nov/2020:10:25:22 +0000] "GET music.mp3 HTTP/1.1" 206 1982193 "http://domain.com/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36 Edg/86.0.622.38"

A Client-Side Packet Trace shows the 206 Partial Content HTTP Response with a RST from Nginx:

I've tried several different browsers (i.e., Chrome, Edge, etc) with the same issue.

The download is successful when browsing directly and not using Nginx.

Any idea why the MP3 download is failing using Nginx?

Much Appreciated.
