Overwatch 2 Error Codes

Overwatch 2's LC/BC/BN codes are nearly all connection and login problems with Blizzard's servers. Here's what each common one means and how to clear it.

Error codes

LC-208 Disconnected from the game server

Cause: You lost connection to the Overwatch 2 servers — network instability or a server hiccup.

Fix:
  1. Restart your router; use a wired connection.
  2. Restart the game and Battle.net.
  3. Check the Overwatch/Battle.net server status.
BC-153 Connection to the server was lost / can't reconnect

Cause: A network or account-service problem stopping you rejoining a session.

Fix:
  1. Restart the game and log back in.
  2. Flush DNS (ipconfig /flushdns) and restart the router.
  3. Scan and repair in Battle.net.
BN-564 General Battle.net connection error

Cause: Battle.net can't reach the Overwatch service — outage, firewall, or region issue.

Fix:
  1. Check the Battle.net service status.
  2. Restart Battle.net and disable VPN.
  3. Allow Battle.net and Overwatch through the firewall.
LC-202 Lost connection to the game server (timeout)

Cause: A timeout reaching the server, often local network load or a server queue.

Fix:
  1. Restart your router and reconnect.
  2. Close bandwidth-heavy apps.
  3. Retry after a few minutes.
Rendering Device Lost / Removed The GPU dropped out on PC

Cause: A GPU driver crash, overclock instability, or overheating.

Fix:
  1. Update your GPU drivers.
  2. Remove any overclock and check temperatures.
  3. Cap the frame rate and lower graphics settings.
BLZBNTBNA / BLZBNTAGT Battle.net agent/update error

Cause: The Battle.net update agent is stuck or its cache is corrupted.

Fix:
  1. Fully close Battle.net in Task Manager and reopen it.
  2. Delete the Battle.net cache in ProgramData and let it rebuild.
  3. Reinstall Battle.net if it persists.
'Sorry, We Were Unable to Log You In' Login/authentication failed

Cause: Blizzard's login service is busy or your session expired.

Fix:
  1. Wait and retry — often a busy login server at launch/season start.
  2. Restart Battle.net to re-authenticate.
  3. Check the Battle.net status page.

Fixes that work for most Overwatch 2 errors

  1. Check the game's official server status page or its X/Twitter — if servers are down or under maintenance, no local fix will help; wait it out.
  2. Fully close and restart the game and its launcher (Steam / Epic / EA App / Battle.net / Riot Client).
  3. Restart your router and, on PC, flush DNS (open Command Prompt and run: ipconfig /flushdns).
  4. Verify or repair the game files in your launcher so a corrupted update is re-downloaded.
  5. Make sure the game and your OS are fully updated — most 'version mismatch' errors are an out-of-date client.
