Fix DayZ Server Not Showing in the Launcher (DZSA)

DayZ server trouble splits into two: the server not listing, and the dreaded mod mismatch on join. Here's how to fix both — vanilla and modded — plus the DZSA-specific quirks and how to stop mismatches recurring.

Open the ports

DayZ needs the game port plus a Steam query port over UDP:

2302/udp   game (default)
27016/udp  Steam query
2303-2305/udp  (used by some setups)

Mods must match — use the DZSA Launcher

For modded servers, every client must load the same mods in the same order as the server. The DZSA Launcher handles this automatically — it reads the server's mod list and loads them for the player. Point players to DZSA rather than manual mod setup.

Connect directly

In DZSA Launcher you can add the server by IP, or in-game use the community browser and the favourite/direct-connect with server-ip:2302. Direct connect avoids the slow browser refresh.

Still not listing?

• Confirm the Steam query port (27016) is open — it's what feeds the browser.
• Check the server actually started (read the server log for mod load errors).
• Make sure the server name/visibility is set in the config.

Open 2302 + 27016 query, use DZSA so mods match in order, and restart the server after any mod update.

DZSA-specific quirks

• DZSA caches server data — a server that just changed name, mods or ports can show stale info for a while; wait or refresh the list manually.
• BattlEye kicks with a generic message when a client mod version doesn't match — this looks like a mismatch but is really a stale client cache; have the player verify/update mods in DZSA.
• A server behind CDN-style anti-DDoS or a reverse proxy needs its real game IP registered with Steam, not a proxy address, or DZSA can't query it.

How to avoid mod mismatches going forward

• Pin exact Workshop mod versions in your server's modlist rather than relying on "always latest".
• Publish and pin your server's mod list publicly (DZSA reads this) so players' launchers auto-sync.
• Restart the server immediately after any Workshop mod update — don't leave it running the old version.
