Live HLS m3u8 stream from encoder server Stutter/Jumps around

I'm trying to run a stream in a roku channel from the following URL:

 
After around 20 seconds of playback it stutters/jumps around. It works on a web browser. I've tested the stream using Roku Stream Tester(http://devtools.web.roku.com/stream_tester/html/) and the issue is present there as well. So I know for some reason Roku devices isn't liking my stream. The stream is generated using a PVI h264 IPTV encoder server. I'm not sure what I'm doing wrong here.

Does anyone know why this is happening? Can someone guide me towards a fix for this?
Thanks in advance.

    I sometimes use cURL or wget to retrieve HLS playlists and segments and your server is doing something weird.  If I try to use wget I get

    --2020-09-18 12:45:29--  (try: 3)  http://96.73.1.110:8080/0_51461.ts
Connecting to 96.73.1.110:8080... connected.
HTTP request sent, awaiting response... 206 Partial Content
Retrying.

    over and over again until the final 404 when the segment is, I assume, automatically deleted.  If I use cURL to retrieve the m3u8 playlist it's fine, but if I use it to retrieve a segment it never completes.

    It may be a red herring, but I've never seen anything like that.

    More useless information - using some code that uses the old SDK it plays fine on my Roku 3 with firmware v9.2 other than some weird glitching at the start of the stream.  Using a different/newer device with newer firmware acts as you've described.
