This is the problem I get during installation of the Minecraft Forge server:
I see the 403 in the log, but I'm not sure how to fix that, or if it can be fixed (if it's an issue with the URL being used, or if it's an issue on Mojang/Minecraft's end). I'm installing using forge-1.7.2-10.12.0.976-installer.jar. Forge installs fine and works fine on single player mode. Just having an issue with the server version.
I have read through the EAQ's, and didn't see a related topic. Please correct me if I've missed something that can resolve this. Additionally, if there's a link that can be provided to manually download the missing components, that would work too.
