When to Call a Professional

If you have tried every step in this guide and BC-101 persists only on your network (not on mobile data or another connection), the issue may be with your ISP blocking or throttling Blizzard traffic. In that case, contact your Internet Service Provider and report that you cannot reach Blizzard servers. You can also open a support ticket directly at support.battle.net — Blizzard support can run server-side diagnostics on your account and escalate routing issues with your ISP if needed.

Frequently Asked Questions

What does Overwatch 2 error code BC-101 mean?
BC-101 means Overwatch 2 has lost its connection to Blizzard's servers. It can be caused by a Blizzard server outage, your internet connection dropping, firewall or VPN interference, or corrupted game files.
Is BC-101 a Blizzard server problem or my internet?
It could be either. Always check Blizzard's server status on downdetector.com or @BlizzardCS on Twitter/X first. If servers are online and other games work fine, the issue is most likely on your end.
Why do I keep getting BC-101 even with a good internet connection?
A stable internet connection doesn't guarantee a stable connection to Blizzard specifically. A firewall or antivirus blocking Battle.net, a VPN rerouting traffic, or corrupted game files can all trigger BC-101 even when your general internet is working perfectly.
Does BC-101 mean I am banned from Overwatch 2?
No. BC-101 is a network connectivity error, not a ban notification. Blizzard uses different error codes to communicate account bans or suspensions. BC-101 simply means your client cannot reach the game servers at that moment.
Will I lose my Overwatch 2 progress if I reinstall the game?
No. All of your Overwatch 2 progress, stats, unlocks, and cosmetics are stored on your Blizzard account servers, not locally on your device. Uninstalling and reinstalling the game will not affect your account data.
