Hi,
The issue stems from a failure to reach the Nginx which loads the VOD module, which is needed in order to play content using HLS.
The problem is here:
GET http://........:88/hls/p/101/sp/10100/serveFlavor/entryId/0_hf3et0j6/v/2/flavorId/0_k7k4h8pm/name/a.mp4/index.m3u8 net::ERR_CONNECTION_REFUSED
Is your Nginx running and does it listen on port 88 TCP?
Also, what is the output for:
mysql> select * from delivery_profile where id in (1001,1002,1003)\G
