Fix Overwatch 2 Error BC-101 Login Failed To Game Server (2025)

Updated: 12/1/2025

You start Overwatch 2, hit play, and instead of reaching the main menu you see Error BC-101 with a message about failing to connect or needing to try again later. Other online games may still work, so it feels like only Overwatch is broken. BC-101 is a general connectivity error that usually signals trouble between your device and Blizzard’s servers, often caused by local network issues, DNS problems, or account sign in glitches.

Method 1: Check Blizzard Server Status And Region Settings

If BC-101 only appears during peak hours or right after updates, wait 15 to 30 minutes and retry. Once login queues and server load drop, many players find that the same connection works with no changes on their side.

Method 2: Reset Local Network, DNS, And NAT Type

On PC open Network settings and set DNS servers to a reliable pair such as 8.8.8.8 and 8.8.4.4, then run Command Prompt as administrator and execute the following commands.

ipconfig /flushdns
netsh winsock reset

Restart your computer after running the commands and then try logging into Overwatch 2 again.

Warning: Avoid repeatedly toggling router or modem power in short bursts, letting devices fully reboot once is better than many partial restarts.

Method 3: Repair Game Files And Re authenticate Your Account

Visit the Blizzard account management page in a browser, go to the Connections section, and confirm that your console profiles are properly linked to the right Battle.net account. If you see outdated or duplicate links, disconnect them carefully and re link following official instructions, then try starting Overwatch 2 again.
