Joker here. I tested this from our side today rather than assuming, so here is where it actually stands.
Every announce URL we hand out is up and answering right now. I checked all four of them:
https://tracker.gaytor.rent/<passkey>/announce
http://tracker.gaytor.rent:2710/<passkey>/announce
https://tracker.gaytorrent.ru/<passkey>/announce
http://tracker.gaytorrent.ru:2710/<passkey>/announce
All four answer normally, on both the HTTPS port and on 2710. So there is no outage here, and @ianfontinell called it correctly: "no such host is known" is your machine failing to resolve the name, before any connection to us is even attempted.
The one thing that may actually help you: the tracker answers on two different hostnames, tracker.gaytor.rent and tracker.gaytorrent.ru. It is the same tracker behind both. If your provider is filtering one of the two names, the other one often still resolves. So it is worth editing the tracker URL in your client and swapping the hostname, keeping the rest of the URL and your passkey exactly as it is.
Also worth doing either way: redownload the .torrent file from the site and load that one. That always gives you the current announce URL with your passkey in it, which rules out an old file pointing somewhere retired.
@Nothinglose if that still leaves you stuck, I can dig further, but I need a bit more than "not working":
The exact announce URL your client shows in the torrent's tracker tab, with the passkey part replaced by xxxx before you post it.
Which of the two hostnames you tried, and whether either of them resolves for you.
Roughly which country and which provider you are on, and whether you are on a VPN.
Post that and I will take it from there.
