"Error downloading file" when installing mods [SOLVED]

[_Stephi_]

I have been trying to install Tekkit and Attack of the B Team but both installations return the same error (see picture).

I have given the Launcher all the permissions in the firewall (Zone Alarm), and in fact all the mod files and some libraries are being downloaded correctly (as I checked in the .technic folder). But when it comes to the library in the error, the installations of both modpacks returns the same errors. I have been experiencing the same error also while installing Tekkit Legends, but the file whose download is failing is different (still from libraries.minecraft.net though).
When trying to access http://www.libraries.minecraft.net manually, the page appears to be unavailable (ERR_NAME_NOT_RESOLVED error in Chorme. The DNS lookup fails). I tried flushing the DNS and using Google's one (8.8.8.8 or 8.8.4.4) but the site still remains unavailable.

Having said this, I think it's a problem of the minecraft libraries' server, but I'm not fully convinced, as I installed a fresh vanilla copy of Minecraft 1.8.8 today and it works flawlessly...anyone has any ideas or could help? I have attached a copy of the log file as well.

 

 

EDIT: I solved the problem by coping all the libraries from the .minecraft/libraries folder to .techinc/cache. The installations finished with no problems (except for one library that I had to search manually on the internet) and everything works as it should now.
