XpathonURL gets stuck

Hi,
I'm trying to scrape URLs from a list of more or less 20000 URLs but I don't get literary any results. The scraping gets "stuck".
The proxies I use are working.
What could be the reason?
Thanks in advance!

What version of Seotools are you using? Can you send the Excel file with the list of URLs to victor@seotoolsforexcel.com? Might be an issue with a list of that size.
