I checked with AHREFS and they have said Cloudflare has made the changes required to allow their IP to crawl our site. However we received the following:
Hello Daniel! We have added new IPs so it looks the audits fail because we can't access your site from those IPs. You need to reach out to your hosting provider and ask them to whitelist this IP range 202.8.4x.x.xx
You can find individual IPs for this range here:
