[Error downloading file for the following pack: Tekkit]

Hello, everytime I try and launch any pack I get this error

"Error downloading file for the following pack: Tekkit

Error Accessing URL: <long URL I cannot copy and paste>.

Please consult the modpack author."

 

Looking at the console while launching Tekkit I receive this:

I have tried deleting 'modpacks' and 'assets' folder multiple times, I've even tried deleting the whole folders, and re-installing TechnicLauncher. Same thing. I'm getting fed up, can anyone help me?
