Guaragaito (he/they)Has Apple Soft Banned Annas Archive?
Perhaps the block isn’t safari but icloud private relay? Which is only on when I use safari?
In that case it would be the archive blocking you for using the relay. I’ve run across a couple sites that block access from iCloud private relay to “prevent spam” or similar, same as if they were blocking a VPN.
Which domain are you trying to use?
