my phone is trying to use an IPv6 address for the game, but my mobile carrier's network has a security or routing error. When the game tries to connect, the network sees this RPKI failure and, in an effort to protect itself, it drops the connection. This is why I'm getting a "timeout" error-the game server is waiting for a response, but the data is being blocked or dropped before it can get through. This is the main reason for problem, Samsung blocking server for online multi-player gaming.
