[URL download .jar file not working]

I tried to download 1.12.2 forge, but when I try launching it I got this.

" Failed to download file.

Name: 1.12-forge1.12-14.21.1.2387.jar

URL: https://s3.amazonaws.com/Minecraft.Download/versions/1.12-forge1.12-14.21.1.2387/1.12-forge1.12-14.21.1.2387.jar

And when I try to download it by copying the link in my webbrowser, it seems to deny access. Any help ?
