Web Scraper stops working once it "could not establish connection"

Web Scrapper stops working after it opens a site that's not working instead of jumping to the next URL. I thought it would continue scraping the other URLs? TIA!

Web Scraper version: 1.29.66
Chrome version: 116.0.5845.188
OS: Windows 11

Sitemap:
{"_id":"A_Mailto","startUrl":["https://www.hifil.co.kr","https://www.hhblower.co.kr","https://www.ijtechusa.com","https://www.inctrl.com"],"selectors":[{"id":"Mailto","parentSelectors":["_root"],"type":"SelectorHTML","selector":"body","multiple":false,"regex":"(?<=mailto:)[^"]+"}]}

Error Message:
