Question

Returns AccessDenied when I try to access a file via a CDN on DigitalOcean Space

So I have been following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-use-activestorage-in-rails-6-with-digitalocean-spaces

I set up Space, and set “File Listing” to the public there. CDN has also been enabled.

The URL generated looks like this: https://my-space-name.fra1.cdn.digitaloceanspaces.com/abcabacabc123123123

As soon as I open it, it gives me AccessDenied. I’m not sure what I’m missing here.

Hi there,

It looks like that someone reported the same problem in the comments section under the tutorial.

When using the CDN, you need to make sure to set the CORS Configuration for your Space. The CORS configuration determines how other sites can interact with your Space. You can set this from the DigitalOcean Spaces dashboard for your particular Space.

The user reported that the issue was the CORS settings and that they had to be loosened a bit for direct uploads to work with the CDN enabled.

Let me know how it goes!

Best,

Bobby
