I was trying to add a sound file to a sketch on Open Processing and it started throwing a 403 error when I tried to trigger the sound. The files are all uploaded to the site and do not have to be accessed locally, so I wouldn’t think it is because of CORS. I have other sketches on this site with sound files of the same file type and this problem does not occur. The browser I am using has stayed the same between sketches. The only thing I could think of was to change the file permissions before uploading, but this did not work.

Can you share a link to the sketch?

Here it is. Now it seems to be throwing 404, despite the file being uploaded and named correctly in the code (I think).

Hmm, loads fine for me in both Firefox and Chrome.
