Yes it is a connection problem. Sometimes the connection file goes stale.

Did you try replacing the gnutella.net file?

Make sure LuckyWire is closed before doing the following.

The .net file extension of the gnutella.net file might be hidden depending on your system settings.

Download the gnutella file: My Files or alternative link gnutella.net

If using Windows XP or earlier:
Click on Start > click on run > type %appdata% into the text field > ok.
You should now see a lot of folders - find the one named LuckyWire, open it & you'll see your gnutella.net file inside that folder. Delete that gnutella.net file & replace it with the one that you've just downloaded.

For Vista or later:
Click the Start button > type %appdata% into the text field > ok.
You should now see a lot of folders - find the one named LuckyWire, open it & you'll see your gnutella.net file inside that folder. Delete that gnutella.net file & replace it with the one that you've just downloaded.

Then open LuckyWire and see if it connects. If LuckyWire does not connect during first opening (wait up to 30 minutes), then close LuckyWire and re-open a minute later. It should connect sometime after the second opening.
