Pluto for Raspberry pi issue

I am trying to get pluto on my Raspberry pi 4 (installed the image version) I've tried searching this forum for detailed instructions but I keep finding post that mention dockers which I don't quite understand. is there some other documentation somewhere I am missing?
I keep getting the following error;
2021/06/28 14:55:23.808324 [ERR] Failed to request m3u for Pluto: Get "": dial tcp connect: connection refused

Thank for any help
