Failed to start application / Error: listen EADDRINUSE: address already in use :::3000

I’ve been having issues since adding my project to Glitch. The most recent is that the application won’t load. I fixed an issue with the browser blocking an unsafe thread and when I came back a few hours later it wouldn’t load at all. Any advice? I’m completely at a loss.

Hello @madeleine-rgr-young, welcome to the support forum!

Sorry you’re having trouble with your project. The “EADDRINUSE” error usually happens when a project is attempting to listen to connections more than once. Be sure that if your project has a call to .listen, it’s only happening once in your code. If you’d like, you can share the name of your project and I can take a look at the code as well.

Oh I meant to include that! It’s madeleine-rgr-young-play-go. This is my first time using Glitch so if that’s not what you meant let me know.

For some reason switching from https to http fixed it. I’m not really sure why?
