Connection Refused? appinventor-sources RunLocalBuildServer

Why does https://localhost:8888 gives me connection refused?

I think the problem is coming from here

It says Server running but if I put localhost:8888 on browser I gives me connection refused, I also tried localhost:9990 but no luck

Is it because I'm running it in root user?

I Don't think the problem is my WiFi since my WiFi is speed

I'm not really good In English srry
