SSL cert error for link.clcik

Hi I have been trying to access the links from webpage and click on them
and capture their web address.

I have done so far capturing the links.

page.links_with(:href => /^https?/).each do |link|
login_page=mechanize.click(page.link_with(:href => /^https?/))
puts(link.href)
end

but when I click on the licks I get below error

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B:
certificate verify failed (OpenSSL::SSL::SSLError)
