Linux localhost port 8080 unresponsive

Question

I have a vuejs app running on my localhost on port 8080, and when I open it in my browser the site doesn't load, and I get the warning by chrome that the site is not responding. I also have a python flask backend running on port 5000, and this works perfectly. Is this a common issue? If so, how do I resolve it? Thanks!

OK let us to change default port and try again
first enter npm run serve -- --port 4030 and now again test http://localhost:4030 if agian not works, all you have to do is modify the portvalue inside the dev block in root of your project, for example <your_project_root>/vue.config.js

    // vue.config.js
module.exports = {
  // ...
  devServer: {
    open: process.platform === 'darwin',
    host: '0.0.0.0',
    port: 4030, // Your PORT you changed !
    https: false,
    hotOnly: false,
  },
  // ...
}
