我发布了与此帖Faraday timeout error with omniauth (custom strategy)/doorkeeper完全相同的标题，因为我只是遇到了同样的问题。我在centOS中测试了相同的代码（我现在在Windows上）并且它运行正常。我目前正在使用puma，而另一篇文章的答案是，我用这个命令运行它：rails s Puma THREADS = 1

这里是应该创建访问令牌的探索操作，但它会一直停留直到超时错误
def explore
client = OAuth2::Client.new(DOORKEEPER_APP_ID, DOORKEEPER_APP_SECRET, :site => "http://localhost:3001")
token = client.auth_code.get_token(params[:code], redirect_uri: "http://localhost:3001/api/v1/me")
respond_with token
end
我已经在github和门卫提供者教程上遵循了omniauth策略教程。正如我之前所说，它运行良好，并在centOS中创建一个访问令牌，但在Windows中我得到这个错误，我甚至没有结果https://gist.github.com/fnichol/867550完成本教程，并尝试了不同的法拉第适配器，几乎相同结果。
PD：非常感谢您的帮助，对我的英语感到抱歉
