How To Resolve Grounded 2 Multiplayer Connection Issues

Dealing with multiplayer woes in Grounded 2 can be a real headache, especially when you’re itching to get into a shared world with friends. Common problems include not being able to access the Multiplayer tab, getting stuck on joining, or crashes that bounce you back to the main menu. Sometimes, it’s just a matter of glitches with your connection, account linking, or corrupted save data. But thankfully, there are some decent fixes that have worked on most setups, and knowing what to check first can save hours of frustration.

Easy Steps to Fix Grounded 2 Multiplayer Not Working Issue

Restart your router and gaming device

This one is kind of obvious but surprisingly effective. Multiplayer can break because of tiny network hiccups, and a full restart resets these quirks. It’s like giving your connection a fresh start. Just unplug your router, wait about 30 seconds (or a minute if you’re feeling cautious), then plug it back in. Then, reboot your PC or console and fire up Grounded 2 again. Sometimes, multiplayer stubbornness just clears up after this.

• Unplug router, wait, then plug back in
• Restart your Xbox or PC — shut it down completely, don’t just sleep mode!
• Launch Grounded 2 and try joining or hosting again

On some setups, this helps the connection stabilize—at least enough for the multiplayer tab to appear or for invites to go through. Note: If this didn’t fix it, keep reading.

Try switching Xbox or Microsoft accounts

If your multiplayer is acting wonky, your account might be caught in a bad state. Logging out from your main account and into a secondary one then back again forces the game to reload your multiplayer info, which can fix invite or join bugs. It’s kind of weird, but in my experience, on some machines this actually kicks the multiplayer into gear.

• Log out of your current Xbox or Microsoft account via Settings > Accounts > Sign out
• Sign in with a different account, maybe a secondary Xbox profile or Microsoft account
• Launch Grounded 2 and test multiplayer — see if the tab loads, invites come in, or friends can join
• Then, go back to your original account and try again

This trick isn’t foolproof, but on one setup it worked overnight after failing multiple times.

Make sure Crossplay and Xbox Live are enabled

This one trips a lot of people up because Grounded 2 relies on cross-platform for multiplayer. If Crossplay isn’t turned on, or if Xbox Live isn’t active, multiplayer features might be blocked. Double-check these in settings:

• Open Settings > Gameplay and ensure Crossplay is enabled
• Verify your Xbox Live connection by launching a different online game or app to confirm you’re signed in and connected
• If Xbox services seem unstable, try reinstalling Gaming Services from the Microsoft Store

Not sure why it works, but after toggling this stuff on, multiplayer often becomes reachable again.

Set your NAT type to Open or Moderate

This is usually the big blocker. A strict NAT blocks incoming connections and invites, making multiplayer sessions unreliable or impossible. Checking your NAT status can be done via Network Settings > NAT Type. If it’s Strict, here’s what to try:

• On your Xbox or PC, log into your router’s admin panel (usually via 192.168.1.1 or similar)
• Forward ports 3074 (UDP & TCP), 53 (UDP), and possibly 8080 if needed
• Turn on Universal Plug and Play (UPnP) in your router — this often helps open necessary ports automatically
• Reboot your router and test the connection again

On one setup, switching from Strict to Open NAT totally changed the multiplayer experience—less lag, invites stuck less often.

Rebuild corrupted shared worlds

If your friends can’t join, or the world just crashes on load, your save might have issues. Sometimes, full rebuilds fix these bugs, especially after crashes or a failed update. Here’s what I’d do:

• Open the shared world, then from the world menu, choose Create Standard Copy
• Launch that copy in single-player mode, then save it anew
• Back in multiplayer, switch the world back to shared mode and re-invite friends

This can reset some broken data that’s stopping multiplayer from loading worlds correctly.

Update Grounded 2 to the latest version

Yep, mismatched versions are a known pain. Everyone in the party needs to be on the same build. Otherwise, sync issues happen, and invites get dropped. Make sure you do this:

• On Steam, right-click Grounded 2, click Properties > Updates, and verify files or check for updates
• On Xbox, navigate to My Games > Manage > Updates
• Ask friends to confirm they’re on the latest — same version, no exceptions

This solves a bunch of connectivity glitches.

Temporarily disable VPNs, firewalls, or antivirus software

Security tools can block game traffic or ports. If multiplayer kept crashing after updates, it might be because of blocking things in the background. Here’s what to try:

• Turn off VPNs and extensions during gaming sessions
• Add Grounded 2 and Gaming Services to your antivirus or firewall’s permission list
• Test multiplayer again, then turn protections back on if it works

Because of course, Windows and network setups love to make things harder than they need to be.

Causes of multiplayer issues in Grounded 2

• Xbox account glitches or login bugs that prevent proper authentication
• Strict NAT types or network restrictions typical of certain router setups
• Missing or disabled crossplay / Xbox Live services, which blocks connection
• Corrupted save data, especially after crashes or server errors
• Server overloads or maintenance — sometimes the servers just aren’t available

Wrap-up

Most multiplayer failures seem tied to account hang-ups, strict NAT settings, or corrupted saves. Going through these troubleshooting steps—restarting, account toggling, NAT adjustments, and keeping everything updated—can usually get you back into multiplayer action fast. If problems persist, hitting up Obsidian’s support or forums might reveal ongoing bugs or server issues at play.

Fingers crossed this gets someone moving again — multiplayer is often the best part of the game, after all.
