Connection refused

In my code: `await ffmpeg.run("-i","http://someurl","output.mp4")`, I got error in this image. But when running manually in terminal: `ffmpeg -i "http://someurl" output.mp4`, I run successfully. I use `ffmpeg.run()` instead of `fetchFile()` method because `ffmpeg.run()` method can pass command to download the segment of video, for example last 10 seconds of video, but `fetchFile()` method downloads full video. How to fix `Connection refused` error.
