Files with parentheses broken in web app
I noticed that all my files with names that contain parentheses say they’re generating proxies indefinitely and have failed downloads. This only happens in the app, the files work fine when I’m using them through the mounted drive.

Hey Lauren, it looks like this is caused by the backblaze S3 API not accepting special characters like parentheses in the filename.
This does seem to be an issue with strictly backblaze, we also want to avoid removing those
parentheses from users’ file names. The signed URL we’re using on backblaze throws a validation error on their end.
I recommend not naming your files with that character or not using backblaze.

Since y’all don’t have any way to easily migrate, we’re definitely sticking with Backblaze.
I’ll rename. Have you submitted a report to them already, or should I do that?

Hey Lauren, we’ve submitted, but it would be great for you to submit one as well.
we do help with data migration if you’re up for an annual plan! Happy to help with this process :D

Great, I have done so. We’re going to stick with Backblaze at this point, it seems safer; thank you for the offer though.

Hi Lauren,
This looks like you may not have set up CORS properly This is why it is likely failing on the downloads. Are you bringing your own storage here?

All other downloads work just fine.

Awesome - could you send the drive ID? This is in drive settings
