Resolved -
The system that handles domain forwarding for error ingestion (IE errors.your-domain.com), started experiencing network disruptions last night around 3AM. During this time, errors sent may have been rejected with a Cross-Origin security error.
The system has been restarted and network errors are no longer happening.
