Part 1: Understanding the Connection Challenges in Blue Protocol: Star Resonance​

As a reboot developed by Shanghai Bokura Network (a Tencent subsidiary), Star Resonance operates primarily on China-based infrastructure, creating significant hurdles for international players. The primary culprits include:

• Geographic distance: Data traveling long physical distances introduces lag, often exceeding 150 ms and causing rubber-banding during combat.
• ISP throttling: Internet service providers may restrict gaming traffic, worsening connection stability.
• Firewall interference: Security software or Windows Firewall can block critical game ports, preventing login or in-game communication.
• Server congestion: Peak hours, particularly during evening times in UTC+8, overload servers, triggering timeouts and disconnects.
