I've been using the Sonic VPN on my Mac using the client for a bit an noticed that some sites have started giving me 403's when trying to use it. I narrowed it down to when I get the IPv6 address 2001:5a8:601:4003:157:131:224:199. When I connect and get other IPv6 addresses (like :198 and :200) the sites work fine. I've gone in and configured the client to block all IPv6 and that clears the issue. One of the sites returning 403s is https://www.reuters.com. Another was a site where the error indicated the site was using AWS Cloudfront. I did a few searches on the IP address to check to see if it was on any block list and only found results saying it was not listed.

Has anyone else see this issue while using the Sonic VPN? Any idea on what might be causing these sites to block that one IPv6 address?
