[Hummingbird] Always have Blacklisted IPs

Our website is on Bluehost, working with MaxCDN. It always has blacklisted IPs which cause our images can't load successfully.

We asked MaxCDN team. They explained that " what happened is your hosting blocked us. We saw that before. What needs to be done is Your hosting needs to whitelist following IP ranges > https://www.maxcdn.com/one/tutorial/ip-blocks/  . Hosting thinks we are spam. But really that is how CDN works"

We whitelisted all IPs in htaccess file. Does this work? Since the IP is blacklisted, why only some images can't load? how to fix this? Here's one of the problem page: https://onlydinosaurs.com/portfolio/ice-age-animal-catalogue/
