Page_load超时无效

Question

我在60秒后出现此错误，因为页面尚未完成，在60秒内加载

我执行的代码

b.element(:id,'Finish').click

60秒后抛出以下错误

C:/Ruby23/lib/ruby/2.3.0/net/protocol.rb:158:in `rbuf_fill': Net::ReadTimeout (Net::ReadTimeout)
 from C:/Ruby23/lib/ruby/2.3.0/net/protocol.rb:136:in `readuntil'
 from C:/Ruby23/lib/ruby/2.3.0/net/protocol.rb:146:in `readline'

 from C:/Ruby23/lib/ruby/2.3.0/net/http.rb:1398:in `request'

所以我把它包含在我的程序中

client = Selenium::WebDriver::Remote::Http::Default.new
client.read_timeout = 120 # seconds
b=Watir::Browser.new :firefox, desired_capabilities: caps,profile: "default", http_client: client

但它仍然有效，

然后我包含了这段代码

browser.driver.manage.timeouts.page_load = 180

无论我做什么，它总是在60秒后失败，为什么会这样？

我把这个问题放在了一般性问题上，但到目前为止还没有答案。
