“Localhost refuses to connect” with npm start

Question

I simply want to work on this Bootstrap project of mine, but I can't because I can't test anything on my local server. In my browser, I get the error 'Localhost refuses to connect'. And under that it says, ERR_CONNECTION_REFUSED. It's also serving it up on port 3443 automatically for some reason when I thought it usually did on port 3000 . Even when I type 'localhost:3000' manually into the url bar, it still refuses to connect. I feel like this is the main part of the problem actually. I don't think I started having these problems until I downloaded McAfee. I've since disabled the McAfee Firewall and McAfee Web Advisor in the meantime. Anyway, I don't know if this helps, but here is the content of my package.json , gulpfile.js , and my bash terminal output when trying to execute 'npm start', respectively:

Figured it out. I deleted cookies, browser history, and cached data. Now once typing 'npm start' in my terminal my app serves up automatically to localhost:3000 instead of localhost:3443, the latter not formerly working at all. I was having to type '127.0.0.1:3000' into my address bar before it would display anything in Chrome.
