Trouble with S3

Running Canvas on our own infrastructure with local file storage. I have spun up a new test server and I am trying to get things to work with S3-based storage.
After modifying the bucket's CORS policy, I am able to upload and download fine. However, the background worker cannot generate thumbnails. Every time I upload, I get:
created at: 2020-02-17 14:28:42 -0700
handler: --- !ruby/struct:Delayed::PerformableMethod object: !ruby/ActiveRecord:Attachment 17 method: :create_thumbnail_size args: - :thumb fail_cb: permanent_fail_cb:
run_at: 2020-02-17 21:28:40 UTC
I have tried this with an S3-compatible service at Linode and with Amazon's actual S3 service, so it's not an issue with a nonstandard S3 implementation. Obviously my key and secret are fine because the main photo goes up to the cloud and is visible in my course files, and can be viewed/downloaded from within canvas.
Any suggestions for how I can troubleshoot this further?
