I'm connected to the internet via Cellular Data on my iPhone. All websites can be accessed. However, when I connect my Mac to my iPhone's Personal Hotspot, some websites can't be reached.

For example, I am able to access https://support.apple.com/ on my iPhone, but the same website leads to a "ERR_ADDRESS_UNREACHABLE" page on my Mac's Edge browser or a "Safari Can't Find the Server" on my Mac's Safari browser.

  • Have you discussed this with your cellular data provider? Does your cellular connection use public address IPv4, CGNAT IPv4, or IPv6? Or some combination?

  • @Gilby Hi! How do I know what public address my cellular connection uses? Aug 27, 2022 at 7:27
  • Tools like HE.NET Network Tools can help. But if you are not a pretty competent network person, it may not help very much. In my case using Telstra, I had to change Mobile Data Network to use a non-default APN (the default is IPv6 only). But I was following instruction from a Telstra support group. You will need to diagnose the issue with your provider or a support group.
