Diablo 2 Resurrected Error Codes

Diablo II: Resurrected's errors are mostly online: "failed to connect to server," "your connection has been interrupted," and the Steam-specific "you have not been online in 30 days." Most trace to Battle.net account linking, network conflicts, or a Blizzard server outage. Here's what each message means and how to fix it.

Error codes

You have not been online in 30 days The game (on Steam) can't verify your online status

Cause: Your Battle.net and Steam accounts aren't linked, so the game can't confirm recent online play.

Fix:
  1. Link your Battle.net account to your Steam account in Battle.net settings.
  2. Launch the game once through Battle.net to refresh your online status.
  3. Verify game files afterward if the message persists.
Failed to connect to server The client can't reach Blizzard's online servers

Cause: A network conflict, blocked ports, or a Blizzard server outage.

Fix:
  1. Restart your PC and router, and renew your IP + flush DNS (ipconfig /release, /renew, /flushdns).
  2. Check the Blizzard/Diablo II: Resurrected server status before troubleshooting locally.
  3. Allow the game through your firewall and disable any VPN.
Your connection has been interrupted The session drops shortly after entering the game (often leaving the Rogue Encampment)

Cause: An unstable route to Blizzard servers or packet loss.

Fix:
  1. Do a full hardware reset: power off PC, unplug modem and router for 1-2 minutes, then bring them back up before relaunching.
  2. Switch to a wired Ethernet connection to reduce packet loss.
  3. Retry after confirming servers aren't under maintenance.
Cannot connect to server / server error The game repeatedly fails to establish an online session

Cause: Server-side load/maintenance or ISP routing problems.

Fix:
  1. Check server status first — if servers are down there is no client-side fix.
  2. Flush DNS and reset your network stack, then reboot.
  3. Test another network (or mobile hotspot) to rule out ISP port blocking.

Fixes that work for most Diablo II: Resurrected (PC — Battle.net & Steam, PlayStation, Xbox, Nintendo Switch) errors

  1. Verify/repair the game files (Steam: Properties -> Installed Files -> Verify integrity; Battle.net/Epic: Manage -> Scan and Repair) — this replaces corrupted files behind most crashes and fatal errors.
  2. Update your GPU driver with a clean install (use DDU), and install the latest Microsoft Visual C++ Redistributables (x86 and x64) plus the DirectX End-User Runtime — missing runtimes and stale drivers cause most launch crashes.
  3. Clear the DirectX Shader Cache (Windows Settings -> System -> Storage -> Temporary files) and delete the game's local shader/cache folder in AppData\Local, then relaunch.
  4. Disable overlays (Steam, Discord, GeForce Experience, Epic) and any third-party antivirus/VPN, and add the game to your firewall and antivirus exceptions.
  5. Check the game's official server/status channels before assuming a local problem — many named connection errors are a maintenance window or outage and clear on their own.

FAQ

How do I fix the 'you have not been online in 30 days' error in Diablo 2 Resurrected?

This Steam-specific error means the game can't verify your online status. The simplest fix is to link your Battle.net account to your Steam account in Battle.net settings, then launch the game once through Battle.net to refresh your status. Verify the game files afterward if the message still appears.

Why does Diablo 2 Resurrected say 'failed to connect' or 'connection interrupted'?

These are network or server errors. Check the Blizzard server status first — if servers are down, wait it out. Otherwise restart your PC and router, renew your IP and flush DNS (ipconfig /release, /renew, /flushdns), switch to a wired connection, and allow the game through your firewall. For the 'connection interrupted' error, a full hardware reset of your modem and router usually clears it.
