我经常在我的机器上的几个主机上得到这个错误,例如:

require 'open-uri'
open('https://google.com').read

Net::OpenTimeout: execution expired
    from /usr/local/opt/rbenv/versions/2.4.0/lib/ruby/2.4.0/net/http.rb:904:in `initialize'

    from (irb):3
    from /usr/local/opt/rbenv/versions/2.4.0/bin/irb:11:in `<main>'

不会发生在其他人身上,比如

open('https://twitter.com').read

rbenv中的Ruby 2.4.0和macOS 10.12.3。还测试了Ruby 2.0.0 -macOS上的系统版本。
当我使用curl或Node的request时,我没有得到任何错误和预期的结果。所以这不是一个被阻止的主机,我的IP也没有被阻止。
尝试重新安装Ruby,重新启动机器,问题仍然发生。
有什么建议吗?

看起来这是一个Ruby如何解析DNS的问题。
添加了require 'resolv-replace',现在它立即打开连接。

我找到了这个问题的另一个原因。有一个网络,其中IPv6被宣布为可路由的,但不是。这导致IPv6尝试使用导致错误。
所以我不得不禁用IPv6。
对于Red Hat Enterprise Linux 7:

# cat /etc/sysctl.d/10-ipv6.conf 
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
# sysctl -p

require 'resolv-replace'也有帮助,但我的猜测是,它只是解决了IPv4,而不是,所以我不想限制应用程序在这样一种方式。

我在docker容器中收到rails应用程序的错误,重新启动docker服务解决了这个问题:

sudo service docker start
