Ruby on rails 使用omniauth facebook登录facebook时出现执行过期错误

自7月3日起，用户无法从Facebook登录。 我正在使用omniauth facebook。我从localhost成功测试了登录（指向另一个FB测试应用程序）。但在生产过程中，应用程序显示此错误：

用户应该能够使用Facebook登录，但由于“Faraday:：ConnectionFailed（execution expired）：”而失败。

从外观上看，您遇到了一个网络问题，Faraday没有设置为等待响应足够长的时间。我能从追踪中真正看出的是，在通往facebook的路上，你遇到了网络问题

我可以考虑检查以下几点：

• 如果您的站点通过HTTPS运行，请确保您的证书工作正常。
  • 检查您的gemfile是否设置为需要与Rails和dependencies版本兼容的特定版本的

    omniauth facebook

  • 延长法拉第的超时长度
  • 在法拉第关闭连接之前，使用类似重试的gem尝试并给网络足够的时间作出响应

其他一些人在omniauth facebook的github上对这个问题发表了评论

谢谢！那太有用了！检查网络连接我通过防火墙中的访问规则来阻止我们从其他国家收到的攻击。禁用一些解决了这个问题。因此，Facebook似乎使用了其中一些网络。非常感谢！
