How To Fix “No Man’s Sky Failed To Join Lobby”

When a co-op session is suddenly terminated for no apparent reason, the ‘Failed to Join Lobby’ message often displays. According to several of the afflicted customers, the game usually crashes after this error message displays.

Method 1: Make Sure There Are No Server Problems.

Keep in mind that a Crossplay Patch has been released for No Man’s Sky, removing any limits on who can play with whom in terms of console or computer. As developers at Hello Games continue to work on the transition to crossplay, the servers have been offline multiple times since that patch was released (in June 2020).

No Man's Sky Failed To Join Lobby

If you think the “Failed to Join Lobby” message you’re seeing right now is related to a server problem, you should look into whether or not other players are having the same problem. Checking registries like DownDetector and Outage is the first step in this study.

See whether there’s a cluster of similar complaints about No Man’s Sky by filing a report. Whether you discover that other players in your region are also experiencing server troubles, you should check Hello Games’ Twitter to see if the company has made any formal statements about the problem.

Finally, if you’re seeing this error in No Man’s Sky on Xbox One or PS4, you may want to check the status page of PlayStation Network or Xbox Live to see whether a problem with the game’s peer-to-peer infrastructure is to blame. When a server problem is ruled out as the cause, however, continue on to the next possible solution.

Method 2: Validating The Game’s Authenticity on Steam

It has been determined that corruption in the No Man’s Sky folder within Steam is a common cause of this issue. Some players who had the same issue have said they were able to fix it by utilising Steam’s options to check the game’s integrity and repair corrupted data clusters.

In case this is the case, you can check the game’s integrity by opening the Properties menu in No Man’s Sky on Steam, as detailed below.

Step 1: Launch Steam and click on the Library menu item.

Step 2: After locating No Man’s Sky in your library, right-click on it and select Properties from the menu that appears.

Step 3: Select the Local Files tab under No Man’s Sky’s Properties screen, and then choose Verify Integrity from the drop-down menu.

Step 4: After you’ve gotten the verification process going, wait until it’s finished before restarting your computer and trying to play the game again.

Method 3: By Using the Same Game Type

It’s also possible that the No Man’s Sky connection problems are being caused by the fact that your game type and your friend’s game type are different. At least one of you probably already took the Experimental path. If this is the case, all you have to do is have a conversation and agree whether you want to play the “Normal” or “Experimental” version of the game.

If you or a buddy are currently playing the Experimental branch and want to switch to the Normal game version, you can do so in the Properties menu of Steam. Turn off No Man’s Sky, launch Steam, then head to the game’s Steam Library. When you get inside, right-click on No Man’s Sky and select Properties from the drop-down menu.

Select the desired beta version of the game from the Properties menu’s Betas submenu. Launch No Man’s Sky again and try the connection once again to see whether the issue has been fixed once you and the friend you wish to play co-op with have both confirmed that you are both using the same version of the game.
