*UPDATE* Just double clicked the 804 install again, all working again..Thanks whoever it was who applied a redstone signal to the webserver, that fixed it! 

---------------------------------------------------

 

Doing a fresh install of Forge 804 today, double click the install.bat and I get this, tried 800, gonna keep going back just in case one of them works...but thought I'd let you know.

Thx Lrns123 for the fix:

open the fml.py

search this:  default_url = 'http://s3.amazonaws.com/Minecraft.Download/libraries'

and put it for:  default_url = 'https://libraries.minecraft.net'

same with:  base_url = 'http://s3.amazonaws.com/Minecraft.Resources'

base_url = 'http://resources.download.minecraft.net'

The resources will need to be updated as they changed the format on the server entirely.

However, you guys should update to the gradle as that's the future, and we're not gunna update anything that's old.

The new Gradle system allows us to update things like this on our end and you devs gets the changes automatically.
