FIX API down?

Is FIX API down? I've been trying to connect but I can't login, it was working about 8 hours ago (about 12:00 CET 10/3/2032), but some minutes later I can't login to my account.

I'm trying to connect to h24.p.ctrader.com, also I've tried this IP 139.162.244.191, but I get no response.

By the way, why the domain name was removed from FIX API dialog?

My fault, I did a small change and I did not receive messages back.
