If you use Infrastructure as Code tools like Terraform, they can overwrite your manual CORS settings. To prevent this, always include the correct CORS policy in your Terraform configuration file.
If your bucket has a configured CORS policy, make sure it permits access from *.encord.com.
Click the Run a test button to test the integration.
Paste the URL of any object in the bucket and click Check Encord can access this URI. If the test is successful a green tick appears next to Encord infrastructure and This machine.
