The test site is just for LW's default port (useful to see whether the default port's being blocked...often by an ISP).

AFAIK Qwest don't block LW, but maybe that's changed?
Try changing ports. In LW tools > options > advanced > firewall config. Change LW's listening port to 64049 (or something in the range of 49152 - 65535). Apply to save a change.
Any ports forwarded within a router & port in the 'manual port forward' box will also have to change.
