Please try to shutdown and restart Apache and MySQL. I'm not familiar with your OS environment, but there are some usual causes for this. You can put ##xampp the connection has timed out## in your favorite search engine to get some ideas what it might be in your case.

Could be your firewall, a security suite, another application took a required port, a running ghost process, a misconfiguration or a XAMPP installation issue.

example:
