"Issue hosting multiplayer game. Check connection"

[DeeKay86]

Xbox One X. NAT OPEN. 500Mbps download and 40Mbps upload.

Never had this issue before, but now when I try to host a multiplayer game it says:

"There was an issue hosting a multiplayer game. Checkyour connection and try again".

I have restarted the Xbox, checked my wired Ethernet network. Checked everything. Xbox Live is online and other games work. No idea what is causing this but I play Grounded every day and this has never happened before.

Please help.

Fixed? - I tried again, and again, and again, and again... It has finally let me start the game! 

No idea what was wrong but will update if this happens again.

Check your NAT type where you test your connection and speed.  Keep testing until it says open. Some games can be picky with that.

Hi, thanks for the comment. I did however say “NAT OPEN” in my original post.

Good idea though, but it wasn’t that
