I have a Nginx setup that caches windows updates with slice for me and it work great 99% of the time. However sometimes I get corrupted cached files, They have what looks like plain html at the end of the file and that is confusing me. I have attached the file to this post as it's only small.
nginx version: nginx/1.16.0
Ubuntu 18.04
running in a Hyper-V VM
I cant seem to work out why this happens or how to reproduce it as after removing the file from the cache and downloading a range request again with curl (even asking for far more than the file has e.g 0-16777215) it seems to just work fine. Is this a problem that I can fix in Nginx configuration? or is it a result of windows updates CDN network behaving badly?
Access log line:

Strange content at end of cache'd file:
<HTML><HEAD><TITLE>Requested Range Not Satisfiable</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Requested Range Not Satisfiable</h2>
<hr><p>HTTP Error 416. The requested range is not satisfiable.</p>
</BODY></HTML>
If there is anything that i should look into I would appreciate the help :)
