Welcome to the Q&A Forum

Hey There! I am sorry for the delayed reply. It looks like this didn't get assigned to our help team, so we didn't see it. I apologize for that! The error you are seeing is for our old crawler, which had some issues crawling certain sites based on security settings. We launched a new crawler on June 7th, and you should be seeing much better data in the Site Crawl section of your campaign now. I hope this helps! Please let me know if I can help you with anything else.
