from origin '<my url>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Was working fine until today. URL identifier has existed in the Platforms section for awhile now and is still listed. The project is in the NYC region. Localhost working fine.

TL;DR
- Cache issue causing CORS errors in project - Update project name or re-add platforms to correct - Check for Appwrite Project ID in client configuration

There might be an issue with your project in the cache. Can you try updating your project name?

Thank you Steven! I had ended up deleting one of the platforms and re-added it and seemed to correct it. I assume that updated the cache.

I'm running to the same issue so wondering if it's the same thing - my app skincare-buddy suddenly started throwing CORS errors. I have two platforms of type "Web" with the hostname of the first being * which used to work and then a second with the specific hostname of the Appwrite deployment but neither let the client query data anymore from Appwrite. Could you check if the cache is messed up here too?

My bad. I broke the app while refactoring and didn't have the Appwrite Project ID set on the client.
