Hi Team and fellow players,
I want to report a serious issue I’ve been experiencing since purchasing Grounded 2.
Right from the beginning, I’ve been completely unable to host my own multiplayer game or join my friend’s server. Every time I try, I get this error:
CreateEndpoint: FailedToQueue: 4301
“There was an error hosting the multiplayer game. Please check your connection and try again.”
Things I’ve Tried (None Worked):
Replugging my Ethernet cable
Restarting PC and router
Disabling firewall / antivirus
Logging in and out of Xbox account
Backing up and deleting local save files
Enabling UPnP on my router
Attempting port forwarding for UDP 3074, 3478-3479, 500, 3544, 4500
Switching between Xbox and Steam versions (if applicable)
Despite trying all of the above, I still cannot join or host any multiplayer session. The issue persists, and I haven’t been able to play the game as intended.
Request:
Please investigate this issue — either on the server side, or in how save files or NAT connection is handled. A clear official explanation or fix is urgently needed.
Also, if anyone else has experienced this and found a solution, I would really appreciate any advice.
Thanks for your time.
