Can't start a game

hello Blizzard, when im trying to create a game it kept showing that im
disconnecting … but my internet is fine, whats the solution for this ?

Hey there,

Disconnections can be caused by a lot of different things. I would recommend giving the disconnection troubleshooting steps a try and then go from there.

If you’re still having issues after trying those steps feel free to run a WinMTR and post the results so we can take a look.
