Edge Server returns HLS Empty Packets

This is weird issue.

I have almost 4-7 Edge Server Pointing to Origin server.

While loading HLS stream, some times Edge Server returns Empty HLS list.

Here is empty list

HTTP/1.1 200 OK
Accept-Ranges: bytes
Server: WowzaStreamingEngine/4.2.0
Cache-Control: no-cache
Date: Thu, 20 Apr 2017 18:46:24 GMT
Content-Type: application/vnd.apple.mpegurl
Content-Length: 25

#EXTM3U
#EXT-X-VERSION:3

Any kind of hint/clue, where to debug or how to debug, would be a great help.

I tried my all possible ways.

Thanks

Hello,

Thanks for contacting the Wowza Community

We would need the log files for this issue. Can you open a ticket and submit the log files of a edge server that had the issue and a timeframe?
