A DayZ 502 “Bad Gateway” error typically indicates that the game’s servers are down or experiencing issues, such as overload or a connection problem with the upstream server.
To resolve it, first check the official DayZ server status or Down Detector. If the servers are operational, try restarting your game, checking your internet connection, clearing your browser cache (if applicable), or refreshing the page and waiting a few minutes.
🔍 Why It Happens
-
Server-side issues or maintenance causing gateway timeouts
-
Stored corrupted data in launchers (DayZSA, mods)
-
Outdated or mismatched mods
-
Inadequate firewall or proxy settings
-
Local network glitches (DNS caching or ISP routing)
✅ How to Fix It
1. Check Official Server Status
-
Visit the DayZ status page or forums to see if servers are under maintenance or experiencing downtime. Many 502 errors resolve automatically when services stabilize.
2. Restart Game & Launcher Completely
-
Fully exit DayZ, close Steam and/or DayZSA launcher.
-
Reopen via Steam and launch the game again.
3. Verify and Reinstall Mods
-
Install only necessary mods fresh through Steam or DayZSA.
-
Unsubscribe from outdated mods and reinstall needed ones. As one user noted:
“Deleted and unsubscribed from all mods … redownload … fixed the issue for me.”
4. Verify Game Files or Reinstall
-
In Steam: Right-click DayZ → Properties → Local Files → Verify integrity of game files.
-
This often restores missing or corrupted launcher or BattleEye components.
5. Run Game as Administrator
-
Navigate to
...Steam\steamapps\common\DayZ, right-clickDayZ_BE.exe, choose Run as Administrator. -
Accept BattleEye license if prompted. This workaround fixed “server unreachable” issues for some.
6. Reset Mods & Launcher Files
-
Clear cached files from the DayZSA launcher or local mod folder.
-
Relaunch and let it sync fresh data from a clean state.
7. Restart Network & Flush DNS
-
Power-cycle your modem/router (unplug 30–60 seconds).
-
On PC, run:
-
Optionally change your DNS to Google (8.8.8.8 / 8.8.4.4) or Cloudflare (1.1.1.1).
8. Disable VPN or Firewalls Temporarily
-
VPN, proxies, or aggressive firewall/CDN settings can interfere with server connection. Disable them short-term to test.

🧩 Community Workarounds
-
One user with recurring official and community server errors said the cure was deleting and recreating their Wi-Fi network—giving them a new IP address, which resolved the issue.
-
Another user emphasized BattleEye updates; running it manually and re-validating files solved repeated disconnects.
