ERROR Game disconnected make sure that port 3659 (UDP) is open.

SOLUTION (This is what worked for me, do not hate if it isn't working for you)

Step by step:
-Go to Control Panel
-Open Windows Firewall
-Open Advanced Settings (on lefs side of window)
-Other window will open and in it you have to go to Inbound Rules (Left side)
-On right side press New Rule, check "Port" and press next
-Set it as TCP (Should be checked automaticly) and press "All Local Ports" than press next
-Allow it (Not "Allow if secured", just allow I have other language in my OS so I have to tlanslate it on my own 😉 ) and press next
-All should be checked, if it's not, chech it all and press next
-Name it as you like and press Finish
-Do same thing but with UDP (New rule>Port>UDP+All>Allow>all>name>finish)
-Than go to Outbound Rules (Under Inbound Rules) and do same thing with TCP and UDP

Boom, it should work (it worked for me) I hope I've helped you.
Have a nice day.

P.S. Sorry for all gramatic issues english is not a language that I use everyday (I use it about 5 times a week when I play multiplayer games 😃 ) but I try to master it 😉
