Hello,
Thanks for using our service!
The error message on the link you provided is from your own web hosting service :
What happened?
This website is using a security service to protect itself from online attacks.
Sometimes web hosting services have security set to very sensitive levels where they think when one of our CDN endpoints fetches a url, it is an automated attack. Our IP addresses are from data centres (instead of residential) and they may have determined that because of that it might be a denial of service attack.
This has happened to a few other people who have reported in the support forums here. I have no control over the web hosting services but sometmies if you ask them to turn down the threshold for these sensitive security settings, it will help.
Alternatively you could ask them to whitelist all the IP addresses used in our CDN servers. You can reach out to us via email to ask for an IP list to request them whitelist.
Thanks
