Hi @Jakelynch 👋

What are you seeing in the logs?  
Also, what version are you running?

We're experiencing the same this issue recently. Its about 50% api request failure with cors problem. We're with 7.6 version

The cors error is Access to fetch at '[https://xxxxxxxx/api/as/v1/engines/xxxxx/search.json](https://xxxxxxxx/api/as/v1/engines/xxxxx/search.json)' from origin '[https://xxxxxx.com](https://xxxxxx.com)' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

No error actually tracked from API logs, all 200 status. Looks like the request was routed to a wrong/failure service.
