Ahrefs lots of timeout errors.

Hi, have any of you experienced numerous ahrefs report errors in December? Suddenly my site according to the report has almost 500 errors with timeout. I checked some pages with page speed insight (and others tools) and for a few pages it happens 2-3s but not 5s to be timeout. One report showed a timeout when checking robots.txt. The site seems to me to be running enough fast, i have not made any major changes to the hosting or the site. Could this be a problem with ahrefs and not page?
