The ARM-R0012 error in ARC Raiders, often referenced as ARMR0002, is a network connectivity issue causing matchmaking failures or preventing players from joining matches.
This error means the game client cannot reliably connect to ARC Raiders’ servers, often due to internet connection problems or server-side issues.
What might “ARMR0012” Refer To
-
Server / Matchmaking Error
-
Players frequently report matchmaking and queue-related errors in ARC Raiders.
-
For example, ARMR0002 is a known matchmaking error when the game client struggles to connect properly to the servers.
-
The “in queue” issue: the game may keep you waiting at the launch/spaceport queue, especially during high server load.
-
Based on player reports, ARMR0012 is being mentioned in similar contexts to ARMR0002 (matchmaking / connection lost).
-
Example:
“The queues takes a long time. … (ARMR0012 Error)”
“…that’s probably what armr0012 error means” (in a crash / lost-connection context)
-
-
Server Overload / Outage
-
According to reports, many of these errors are tied to server-side issues: high player load, matchmaking services struggling under surge, or backend instability.
-
News outlets also point to recent outages: The Times of India reports that Arc Raiders recently had a “brief outage” in the U.S., with users reporting connection / login failures.
-
Some of the error behavior (for ARMR0012) may be symptomatic of the login / matchmaking queuing system back-ended by server capacity and throttling.
-
What You Can Do to Try to Fix / Mitigate It
Here are steps based on community advice and known tactics for similar matchmaking / connection errors:
-
Be Patient in Queue:
-
If you’re stuck on “in queue” or you get ARMR0012, try waiting a bit (5–10 minutes or more) on the queue screen instead of quitting / restarting immediately.
-
-
Restart the Game Once:
-
Some users say doing a clean restart of the game client (completely close + relaunch) helps reset your party / matchmaking state.
-
-
Avoid Spamming Matchmake / Re-queue:
-
Constantly exiting and rejoining matchmaking can worsen the issue. Back out only once if you think you’re stuck, then retry after a short wait.
-
-
Verify Game Files:
-
On PC (such as via Steam), verify the integrity of game files. Corrupted or missing files may trigger weird behavior. (Note: this is a general tip and has been suggested by players for other errors.)
-
-
Check Your Network:
-
Ensure your firewall isn’t blocking the game or its services.
-
Restart your router / modem.
-
If possible, use a wired connection (Ethernet) rather than Wi-Fi, to avoid latency or packet loss.
-
-
Keep Drivers Updated:
-
For PC users: Make sure your graphics drivers are up to date. For instance, NVIDIA released a Game-Ready driver for ARC Raiders.
-
Also ensure other system/network drivers are current.
-
-
Report to Support / Bug Forums:
-
Check Embark Studios’ support or ARC Raiders’ official channels.
-
Use the game’s bug report or feedback option.
-
Join community Discords or Reddit: if many people are seeing the same error (ARMR0012), reporting it there helps the devs track and prioritize fixes.
-
Conclusion
-
ARMR0012 seems to be a matchmaking / connection error, likely tied to server load or backend matchmaking infrastructure rather than a client-only bug.
-
It’s not well documented officially yet (or at least not widely), so most of what we know comes from player-reported behavior.
-
The best immediate strategy is patience + retry carefully + report if it persists.
