Set up CORS

Configure your CORS settings so that Ango Hub can safely connect to your buckets.

By default, Ango Hub cannot request resources from your cloud storage and display them in the browser due to CORS policy restrictions. To solve this, Ango Hub's domains need to be included in the CORS headers.

Here's how you can add Ango's domains to your CORS headers.


  1. From your AWS account, go to the S3 Management Console.

  2. Click on the bucket you'd like to connect.

  3. Go to the permissions tab.

  4. In the CORS section, click on Edit.

  5. Paste the following text in the field that pops up:

        "AllowedHeaders": [
        "AllowedMethods": [
            "GET", "POST", "PUT", "HEAD"
        "AllowedOrigins": [
        "ExposeHeaders": []

6. Click on Save changes.
