Stream is Offline ALWAYS

Hi @jess
believe me i read and research before posting or replying, i have read all the mentioned links days before. two questions here;
#1what is the use case of live entry, dash hls ,where we will get the rtmp url and stream name?
#2https://knowledge.kaltura.com/obs-studio-and-kaltura-live-streaming according to kaltura doc, its possible to directly stream from obs studio to kaltura, which is answers my first question i think.
now streaming the way the link explain with manual entry is usefull if you have a m3u8 file , but what i need is rtmp live stream directly to kaltura, thats why i been trying with live entry dash hls, and then taking the provided info rtmp://@PRIMARY_MEDIA_SERVER_HOST@:@PRIMARY_MEDIA_SERVER_PORT@/kLive/?p=100&e=0_dosbbbjw&i=0&t=6e2124eb and the Stream Name 0_dosbbbjw_1 and put them into obs studio , as mention ed here by kaltura docs, https://knowledge.kaltura.com/obs-studio-and-kaltura-live-streaming.
dose that make a sense ?
Thanks.
