I tried to explore Quasar Framework. I download node.js and quasar.cli already. i managed to create project, but when i "quasar dev" in my quasar file, it pop up the errors.

In Windows use the following steps:

  1. Open PowerShell as Administrator.

  2. stop winnat with the command:

net stop winnat

  1. start winnat again with the command:

net start winnat

I recently had this error and it resolved when I restarted my machine.

If that doesn't work for you I would try port 80 as a quick check to see if it is a problem with a closed port. Port 80 is for HTTP so it should be open.

quasar dev -p 80

If that works, then port 8080 might not be setup to run your local server.

To check port availability I use nmap (https://nmap.org/). If you install it and want to check a port from the command line run something like:

nmap localhost -p 8080

Port 8080 was not available in network , issue could be resolved by updating dev property in quasar.config.js

devServer: {
      // https: true,
      //port: 8080,
      open: true // opens browser window automatically
    },

Uncomment port and change the default port number, for e.g. port: 8089
