Cannot access forum when using a VPN

In recent days I get this error which goes away if I disable my VPN. Is this intended behaviour?

It's not any VPN, as I can still sign into the forum on a VPN. But it would not astonish me if CloudFront, which Intel is apparently using here, has a list of VPNs it doesn't like. I've seen this on a few other sites.

Indeed I am using a legitimate, reputable, and highly-rated VPN service that is rather well known! I will dig a bit on google

Having looked at this is seems CloudFront clobbers a whole range of VPN stuff using pretty arbitrary criteria. If I want to access the forum I have to bypass the VPN or maybe start messing with obfuscation.

I have the same issue with my internet provider address range. In my case, using a vpn solve the problem.

According to my ISP, it seems to be the AWS-AWSManagedRules AnonymousIpList list
