Starting last week Friday, our keys for our account totally stopped working with the below error:
Failed to load https://www.mapquestapi.com/directions/v2/routematrix?key="key value": Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://<URL>/' is therefore not allowed access.
When we plug in the keys that our development team uses, everything works. While using our development's teams keys provides a workaround, we need to fix our account keys.
Could someone shed some light as to what may have happened, and how we go about resolving this?
