Hey @hada park, I know it’s frustrating and we’ll help you out. I am curious right off the bat why your urls are missing the 8 at the end of M3U8? You only have M3U? Is that just a typo? as an example- this is the url layout for AWS ---

yes It is a typo. It seems that the last character was not selected while copying url. I still have not solved the problem. ---
