Is Darktide error 9999 ruining your run? Use these quick, practical fixes to bypass matchmaking lockouts and get your squad back into the fight fast.
There is nothing quite as frustrating as gearing up for a tough run in Tertium, rallying your squad, and getting abruptly slapped with Warhammer 40k Darktide error code 9999 right as the mission is about to launch.
If you are running into this issue, you already know it acts as a total roadblock. This error drops you directly from the matchmaking server, completely halting your progression and dumping you back into the Mourningstar. Whether you are playing on a PC via Steam or holding the line on your Xbox, getting locked out of your session is a massive headache.
Fortunately, you don’t have to wait around indefinitely. Below, you will find practical, step-by-step solutions to help you bypass this error and get back into the fight, whether the hiccup is on your local network or a larger issue on Fatshark’s servers.
What is Darktide Matchmaking Error 9999?
At its core, Darktide matchmaking error 9999 is a backend connection error. This simply means there is a communication failure between your personal game client and the official matchmaking servers attempting to assemble your lobby.
You will usually see this pop up during moments of heavy server load, or right when you are in the middle of forming a new squad. More specifically, it frequently triggers when a team composition lockout occurs just before the mission transition sequence. The game struggles to verify the current players in your strike team, panics, and safely disconnects you to the main hub rather than loading a broken instance.
Is Darktide Down Right Now? Check Server Status First
Before you go tearing your setup apart, resetting your router, or reinstalling the entire game, take a breath. There is a very good chance the problem isn’t actually your fault. When error 9999 hits, it is frequently a widespread issue affecting thousands of players at once.
If you are sitting there wondering, “Is Darktide matchmaking down today?” you need to look at the community hubs first. Fatshark’s backend services can sometimes buckle under heavy traffic, especially right after a major patch drops or during peak weekend hours. When the mission terminal breaks on their end, the player base notices instantly.
To check the current Warhammer 40k Darktide server status, here are the most reliable places to look:
- The Official Forums: Your first stop should always be the Fatshark Technical Support forums. The developers are pretty good at pinning an “Acknowledged” or “Investigation” thread at the top of the page when massive server outages or connectivity bugs occur.
- Social Media & Community Hubs: A quick glance at the Darktide Subreddit or the official Darktide X (Twitter) account will instantly tell you if others are getting booted out of their lobbies. If the servers are struggling, you will see a flood of posts about it within minutes.
- Platform Status Pages: Sometimes the game servers are perfectly fine, but the platform you are playing on is having a meltdown. If you are on PC, double-check Steam Status to make sure the Steam network hasn’t dropped. If you are playing on console, verify the current Xbox Live Status.
If you check these links and see everyone asking, “Is Darktide down right now?” then your best move is to just go grab a snack and wait for the developers to roll out a fix.
However, if the servers look totally healthy and you are still the only one getting locked out at the mission terminal, it is time to take matters into your own hands.
How to Fix Darktide Error 9999 (Step-by-Step)
While Fatshark regularly deploys hotfixes and server-side updates to address backend issues, you don’t always have to sit around waiting for a permanent patch. Sometimes, a few quick client-side adjustments can force the game to bypass the error and load you into your mission.
Try these proven troubleshooting steps to clear out any lingering network glitches.
1. Restart Your Game and Launcher
The easiest and most common fix is forcing a completely fresh connection to the game’s servers. Don’t just back out to the main menu—you need to close the game entirely.
If you are playing on PC, go a step further and fully exit Steam or the Xbox app. Make sure it is completely closed out in your system tray, not just minimized. Reopening your launcher forces a full refresh of your Steam network connection, which frequently resolves temporary communication hiccups between your PC and Fatshark’s matchmaking service.
2. Rebuild Your Strike Team
Because error 9999 is so closely tied to how the game handles team composition lockouts, the issue might actually be bugged lobby data. If players joined, left, or swapped characters right before you interacted with the terminal, the servers can easily get confused.
If you keep getting booted, disband your current strike team entirely. Have everyone return to their own Mourningstar instances, and then reform the group from scratch. Letting a different player send the invites and act as the host can serve as a highly reliable Fatshark error 9999 temporary fix while the developers work on a permanent solution behind the scenes.
3. Perform a Router and Modem Reset
If resetting your software doesn’t work, the problem might be localized to your home network. A stale IP lease or a minor data packet jam can interrupt your connection just enough to cause a complete matchmaking failure. A simple power cycle can usually clear this up.
Here is exactly how to do it:
- Unplug the power cables from both your modem and your router.
- Wait for at least 30 to 60 seconds. This gives your hardware enough time to fully drain any residual power and clear its internal cache.
- Plug your modem back in first and wait a minute or two for the connection indicator lights to completely stabilize.
- Plug your router back in and allow it to start broadcasting your network again.
- Reconnect your PC or Xbox and launch the game.
Taking a few minutes to ensure optimal Xbox connection stability or PC network health is often all it takes to clear up stubborn, lingering communication errors and get you back into the fight.
Darktide Error 9999 in Havoc Mode
If you’re primarily running into this disconnect while trying to tackle end-game content, you are definitely not the only one. Ever since the Grim Protocols update dropped, Darktide error 9999 Havoc mode lockouts have been a massive thorn in the community’s side.
Because of the unique way this specific mode handles matchmaking, it requires a slightly different approach if you want to get your squad successfully loaded into a run.
Why Can’t I Host a Havoc Mission in Darktide?
You get your squad together, walk up to the terminal, and the game just kicks you out. If you’re constantly asking yourself, “Why can’t I host a Havoc mission in Darktide?” the answer usually comes down to backend verification checks.
Unlike standard missions, Havoc requires the matchmaking server to perform incredibly strict eligibility checks before it builds your lobby. It has to verify everyone’s operative level, item ratings, and current Havoc clearance. If anyone in your strike team swaps a weapon, changes their operative, or briefly drops connection right as you interact with the terminal, the server panics. It detects mismatched lobby data, aborts the launch, and slaps you with the 9999 error code to prevent loading a broken instance.
Is My Havoc Progression Safe?
Naturally, the biggest fear when you get booted from an end-game lobby is losing your hard-earned progress. Thankfully, getting disconnected by this specific error does not wipe your Havoc assignment progression.
Because the crash happens before the mission actually initializes, the game doesn’t count it as a failed run. Your clearance level and your team’s current assignment order are completely safe. You will just be standing back in the Mourningstar, ready to try again.
The Best Workarounds for Havoc Lobbies
While the developers are actively smoothing out these end-game server checks (which you can keep track of over on the official Darktide patch notes board), the terminal can still act up.
If your game absolutely refuses to let you host the session, try these two specific Havoc workarounds:
- Lock in your loadouts early: Make sure everyone in your group has their weapons, talents, and operatives completely finalized before anyone interacts with the Havoc terminal. Do not tweak your gear while the lobby is queuing.
- Pass the torch: If the error persists, disband the strike team completely. Reform the group, but have a different squad member send the invites. Let them walk up to the terminal and act as the host. Swapping the host is currently the most reliable way to bypass bugged lobby data.
Related Connection Issues: Error 2001 and Eligibility Bugs
While you are actively troubleshooting matchmaking failures, you might run into a couple of other notorious bugs that frequently show up alongside error 9999. If the game throws another roadblock your way, here is exactly how you can handle it.
Tackling Darktide Error 2001
If you are getting hit with Darktide error 2001 and 9999 back-to-back, your local network is likely struggling to maintain a stable connection to Fatshark’s servers. Error 2001 is a broader disconnect issue that can happen mid-mission, during loading screens, or even while you are just standing idle in the Mourningstar.
To fix this, you will want to look at the health of your home network. Many players on the Fatshark Support Forums have noted that Darktide is incredibly sensitive to minor packet loss over Wi-Fi. If possible, switch to a wired ethernet connection to instantly stabilize your game. If you are already hardwired, flushing your DNS via your PC’s command prompt can clear out stale connection data and stop the constant disconnects.
How to Fix “Failed Participant Not Eligible”
When queueing for Havoc mode, you might successfully bypass error 9999 only to get slapped with a prompt stating a player in your party is not eligible.
If you are wondering how to fix failed participant not eligible Darktide errors, you need to check two specific things:
- Check Prerequisites: Ensure everyone in your current lobby has actually completed a Maelstrom mission, spoken to Dukane, and claimed any pending Havoc Rewards caches. If even one player has an unclaimed cache, the terminal will lock the entire squad out.
- Clear the Ghost Party Bug: If everyone is fully qualified but you still see a massive padlock icon on the terminal map, you are likely dealing with bugged lobby data. The game mistakenly thinks you are still in a previous, unfinished run. To clear this out, open the Havoc terminal and press “R” on your keyboard (or the console equivalent) to abandon the ghost run. While this unfortunately costs you one demotion point, it immediately wipes the bugged data and allows your squad to finally launch the mission.
Conclusion
Dealing with Darktide disconnected from server 9999 messages is an incredibly frustrating way to spend your gaming session, but you don’t have to let it ruin your night. By restarting your game, completely rebuilding your strike team, and taking a moment to reset your network hardware, you can usually force your way past the broken matchmaking lobby and get back to purging heretics. If you are specifically trying to dive into Havoc mode, remember that simply swapping the host or clearing out bugged ghost lobby data is often the quickest way around the terminal’s strict server checks.
