how to host m3u8 files

recently i was experimenting around live streaming techniques and i found a site hosting live channel and i found that the player was hosting from a link ending an extension with .m3u8 like (eg: http://xyz.xyz/xxxxx/xx.m3u8) and i download that file and played using vlc it worked fine and i also tried playing the same m3u8 from the example link above, the video streamed n played and then the m3u8 files that i had downloaded before i upload it into cloud and generated a link for m3u8 and tried to stream with that uploaded m3u8 link . the player was unable to play i wanted to know why this happened just for some knowledge and how can i stream that m3u8 file from my own cloud host (ps: my hosted file was on public mode of access permission)
