On Wednesday, 12/05/2018 I changed the shipping module on the back end of our website to allow free shipping on orders greater than $50. We are running a 20% discount coupon this week, but since we don't allow a customer to use more than 1 coupon at a time, our free shipping code could not be used with the 20% discount. Customers wanted to also get the free shipping over $50, so we changed the shipping module to automatically do free shipping. I then tested our website and it showed free shipping for orders over $50 along with the other UPS shipping options.
It showed regular ground shipping rate for orders under $50, along with the other shipping options. Sometime later, our website stopped showing any UPS shipping options. Instead we got the message: "We are unable to obtain a rate quote for UPS shipping. Please contact the store if no other alternative is shown."
I have not been able to restore the interface with UPS.
How do we get the UPS shipping to work again?

Thank you,
Chris the baker
