This happens every single major patch and is an issue that SE creates.

It mysteriously resolves after about the first week of each major patch as well, so all you normally have to do is wait or use a VPN.

I've seen easily 30 major patches and this exact issue has triggered on 100% of them. So don't go letting SE or their sycophants gaslight you into thinking something unusual is happening on your end. It isn't.
