[SmartCrawl Pro] Cannot do SEO checkup in Cloudinary CDN

I cannot do the SEO checkup, I get this info:
There was an error crawling https://www.brandeddrones.com/, we weren't able to get meaningful result.
I think it can be connected with the fact, that the web is behind Amazon Web Services Cloudinary CDN. But I have no idea why - there are not WAF rules to block any traffic.
