I'm consistently getting this error on several hosts on my machine, e.g.:
require 'open-uri'
open('https://google.com').read

Ruby 2.4.0 from rbenv and macOS 10.12.3. Tested also with Ruby 2.0.0 - the system version on macOS.
I get no error, and expected results when I curl
or use Node's request
. So this is not a blocked host, and my IP isn't blocked either.
Tried to reinstall Ruby, restart machine, and issue still occurs.
Any pointers?
Looks like it's a an issue with how Ruby resolves DNS.
Added require 'resolv-replace'
and now it's opening connections immediately.

I received error from rails application in docker container, and restarting docker service solved the problem:
sudo service docker start
