Problem description

Since updating Wappler I can no longer get the server to run. I haven’t made any changes, so this was working fine before the update.

Error: Error: listen EACCES: permission denied 0.0.0.0:3000

events.js:288
      throw er; // Unhandled 'error' event
      ^

  errno: 'EACCES',

  port: 3000
}

And no, the port is not opened elsewhere, I checked, and I do not have Windows firewall enabled on my private network connection. I also tried running Wappler as admin. As I said, this was working before the update.

Update: Seems for some reason all ports 3000-3040 are no longer accessible. I have no idea why this is now, but setting a port above 3040 seems to work. Will have to figure out why those ports are inaccessible, since the ports are not in use (at least netstat -ab shows no process using them).
