Fed Ex Tracking no longer working?

[concession-supply.com]

We ship via UPS and Fed Ex and recently noticed that customers can no longer track Fed Ex shipments. Has the code not been updated or is their an issue at Fed Ex? The link provided by the 3dcart no longer tracks Fed Ex packages. However, the tracking number can be used on the Fed Ex site to track the package.

Are you seeing this in the shipment emails or in the customer account area?

In the edit order page.
There is a hyperlink built on the order page that looks like a ? mark
It no longer works. The response is "No tracking information available".
The UPS links work correctly.
Check yours to be sure.
