Why copybara and poltergeist after entering the page in a loop can't go to the next item?

Welcome!
There is a page with a list of URLs that need to walk, go each to make something(perhaps, too, to link to it). The problem is that after the first link, the next no longer comes.

url1 = '....'
@browser = Capybara.current_session
@browser.visit url1
@browser.all '.registerBox table'.each do |item|
 link_on_uid = item.first.descripTd dt a'
 url2 = link_on_uid['href']
 puts url2
 @browser.visit url2
 @browser.all('.boxWrapper>table>tbody>tr').each do |tr|
.....
end
 puts 123
end

The code like this. Run in the console, after 123 puts for a long time nothing happens, and then the process ends without errors. The result in console only two strings - the url of the page and 123.
If you comment out the link in the variable url2 that returns all the necessary links from the page.
