Can't seed my .torrent file created using create-torrent

I use NPM package create-torrent to create a torrent file.

var createTorrent = require('create-torrent')
var fs = require('fs')
createTorrent('./files/Snatch.S01E06.720p.WEB.rus.LostFilm.TV.mp4', function (err, torrent) {
    if (!err) {
        // `torrent` is a Buffer with the contents of the new .torrent file
        fs.writeFile('./files/Snatch.S01E06.720p.WEB.rus.LostFilm.TV.mp4.torrent', torrent, (err) => {
            if (err) throw err;
            console.log('The file has been saved!');
        });
    }
})

After The file has been saved! I seed my file:

const WebTorrent = require('webtorrent');
const client = new WebTorrent();
const fs = require('fs');

fs.readFile('./files/Snatch.S01E06.720p.WEB.rus.LostFilm.TV.mp4.torrent', (err, data) => {
    if (err) throw err;
    client.seed(data, function (torrent) {
        console.log('Client is seeding:', torrent.magnetURI)
    })
});

I saw

Client is seeding: magnet:?xt=urn:btih:aa5603103e011129e1244ce355e6ec75cf363789&dn=Unnamed+Torrent+1491935616105&tr=udp%3A%2F%2Fexplodie.org%3A6969&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Ftracker.empire-js.us%3A1337&tr=udp%3A%2F%2Ftracker.leechers-paradise.org%3A6969&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337&tr=wss%3A%2F%2Ftracker.btorrent.xyz&tr=wss%3A%2F%2Ftracker.fastcast.nz&tr=wss%3A%2F%2Ftracker.openwebtorrent.com

but when I try to download my torrent on my and my wife's laptop but I always see 0 peers.
