FLV files will not load for streaming

Hi There,
I have newly installed Subsonic to my NAS and for the most part it is working quite well.
When I connect to the media server via web browser (MS Edge) music files play well and I can play mp4 videos but not FLV files which I have allot of.
When I attempt to play any of those, it tries to load it but always gives me the error: hlsjs: Video file not found
Need some help here as I understand that Subsonic server should be able to play/stream these files. I have tried 3 different browsers with the same result.
Thanks.....
