How to download private repo release asset binaries

I have a private repository and I want to be able to download assets from a release using cURL but I get a 404 when trying access it outside of a browser, even if I am correctly authenticated with a personal access token. I am able to download the 2 source code archives without any issues. It is ONLY the additional binary (a jar file) that fails. See links below:

This works:
https://github.com/PhilipsRespironics/eureka-server/releases/download/v0.1.5.RELEASE/eureka-server-0.1.5.BUILD-SNAPSHOT.jar
This Fail
https://github.com/PhilipsRespironics/eureka-server/archive/v0.1.5.RELEASE.zip

I have verified that the personal access token is working because I am able to download the source archives with it, but it fails without it. It is only the custom binary that fails. Has anybody here been able to do this?

Also, as a side note, my end goal is not to use cURL, but Terraform.
