If you can't reach that page then that's not good! It's either due to a connection device like a modem/router or your isp provider has detected you using p2p share program & has blocked the port. Go to LW's preferences >Advanced>Firewalls & try another port number in the Listening Port section. Try these one by one: 3500, 1203, 80, 20282, or 443. Don't forget to press the apply button after changing it. After this go to File>Connect or disconnect, wait a minute, then connect. Give it 20+ mins to try to connect for each one.
