Using Basic Auth to retrieve jobs via API results in Cloudflare 503

Our Job retrieval for 50+ ServiceM8 Accounts stopped yesterday after being intermittent. Our system cannot connect to the API service. We're nowhere near the 20,000 limit per account.

I tried connecting via Postman and I'm getting this 503 Error:

The Lambda function associated with the CloudFront distribution is invalid or doesn't have the required permissions. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner.

If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation.
