Part 1: What is Chrono Odyssey Error Code 100150

Chrono Odyssey Error Code 100150 is a server-related error that typically occurs when a player attempts to log into the game but fails to establish a connection with the Chrono Odyssey servers. It appears as a prompt with no detailed description, simply indicating that the user is “Unable to connect to the server”.

Unlike many other in-game errors that might relate to in-game bugs or corrupted files, this one is fundamentally a network communication failure. During the Closed Beta phase in June 2025, numerous players reported the issue when trying to access the game across North America, Europe, and Asia.

• Conflicts with firewall or antivirus software
• Incorrect DNS settings
• Outdated network drivers or system files
