Welcome @Bucephalus !
It seems that your Internet is broken 
Or in other words: the error message implies that you can’t connect to the URLs you are using. Maybe you are behind a proxy?
Another thing:
Don’t post screenshots, they are difficult to spot and read.
Just do like I do here:
julia> using HTTP
julia> HTTP.request("GET", "http://httpbin.org/ip")
HTTP.Messages.Response:
"""
