My home ISP does CGNAT for IPv4, but provides native IPv6. I can use IPv6 just fine to access most of my resources, except for one specific server. I can access the server over IPv4 from my home network, and either over v4 or v6 from other networks I’ve tried. But I can’t access it over IPv6 from my home network.
What could be the problem here? Where do I begin to diagnose it
Can you test that site from someone else’s ISP, and from someone else near you on the same ISP?
From other ISPs it works fine. I haven’t checked from someone else using the same ISP, but that’s a good idea. Thanks!
