Factorio Forums

The website now appears to require you be logged in to your factorio account to download the headless server binary. This makes getting that binary onto headless servers more complex as we now have to download it locally then upload it to the server instead of just using wget or curl to grab it directly.

Have you tried embedding creds in the curl string?

I doubt it would work because the devs would have to code for it but something like the below is common.

curl http://username:password@normal.dwnload.url.com
