Hey, well done for persisting with the problem solving and reaching a fix.
Was it this suggestion?
Do you have IPv6 enabled on your router?
If so, another experiment would be disabling that for a while.
We've seen one or 2 posts where IPv6 and Hikvision cameras and Apple are a strange mix.
No idea of the underlying cause though.
