Closing. Not reproducing anymore.

In case anyone falls over this again (as i did).

We had (still have..) the same issue here. But only from select internet connections (our office).
Possible workarounds:

• different internet connection (mobile hotspot, ..)
• switching out the provided DNS server for google (8.8.8.8)

I had the same issue when using a mobile hotspot provided by iPhones over Verizon. Adding Google as my DNS server resolved.

Thanks very much @maxigs God bless you!! I was installing RVM with jruby, rails and puma and faced this error. So, as you instructed, I pointed my DNS to Google and the error gone away.

This works for me. Tks

Switching the DNS to google solved it.
