Youtube does not like to get crawled. If your site has many links and a small interval between checks, you may reach some threshold and will be blocked.
Check pages with youtube-links one by one and with a higher interval
Exclude links to youtube from monitoring: --ignore="\Qyoutube.com\E"
Links to linked.in are heavily protected against automatic crawling and return 999 instead of 200 if their pages are requested by a crawler.
Exclude external linked.in requests from the check: --ignore="\Qlinkedin.com\E"
