As for the recursion I have three choices, Any, Local Nets, or Local Host. It is currently set to Local Host. I changed it to Any for a test but it didn't make any difference.

This use to work, it just started failing recently.
It appears you're dealing with a different problem? Is there anything you cache folder for error logging (I am assuming you're using Zen Cart 1.3.9)? Were you working on anything prior to your shipping quote not working? Are you experiencing the same thing on your test site (I am assuming you have one)? If you turn on UPS is that also not working? Your payment gateway working i.e. people can still checkout with PayPal.

If PayPal is working on your site you definitely are not dealing with the problem I had. If what I was thinking is true, any services that needs to access external site, like usps, ups, fedex, paypal, google checkout, etc. will NOT work on your site. If one is working then you situation is different.
