MCreator never wants to install (please help me)

I know it's no use posting here because the community is pretty bad and nearly dead, but I'll try to anyway because I am out of awnsers. 

Everytime I try to install Mcreator 1.7.5 it complains about having no internet connection, it's driving me mad.

Here's the log:
