A-AND-A won't work

[caden3ds]

When I try to connect to A-And-A, it says "Starting DNS Service" then "Stopping DNS Service", goes back to ""Starting DNS Service" and just loops. I am using the default settings, except for a blacklist which blocks some Apple websites for preventing revoked apps.
So far I've tried reinstalling, backing up and restoring my device, and clearing cache.

It works for me on both an IPv6 only network and an IPv4 only network. No issues at all with a-and-a.

No issues with a-and-a here either.

The issue you are reporting seem to be unrelated to a-or-a. Or maybe, for some reason, your router or ISP is blocking that network.
