i'm trying to make a lobby system without using lobby or relay, and clients can seemingly connect to nonexistent servers. is there a way to check if a server is being hosted under specific port/ip before letting clients connect (or other ways of controlling client connection)?

The best you can do is Ping the address to see if its there. But there is no way to know what is running on it except by trying to connect
