Server Server does not appear in the list, etc

Hello guys, so I rented a Cloud (VPS) to host my server, and it worked perfectly, but no one enters it, I can enter with the IP added to favorites and clicking, but through my list I have not found my own server, I I'm from Brazil, my Cloud is the United States, when I was staying on my computer, accessed the normal people, just slow to come in, but accessed, even now, no one goes, what could it be?


I added the GameTracker site and it detects my server normally.
