How do I troubleshoot a 404 error when trying to use the GitLab API to download a raw file?

I am attempting to use Terraform to download a raw file from a private repo. However I am getting a 404 error.

Logs:

I'm not sure if the 404 is valid, or if the connection refused means I have the wrong endpoint/token/port?

I'm not sure why I'm getting the port 80 connection refused message. The URL is HTTPS and I am using --location.

Solution

Use a lowercase -o to specify the local file name. Your uppercase -O does not take an argument, and specifies that you want to use the remote filename when saving the output.

I presume that curl interprets './.terraform/REDACTED/src/manifest.yml' as the first url to fetch rather than as a file name.

If you run your curl command with the -v flag, you may see for yourself.
