Here is what I did to get my server up and running and to be able to connect to it.
My server is running on a seperate PC but this Guide should work the same if tyou want to run it on the same PC you are playing on.

I will NOT be answering questions, if you need help there is lots of support here.

A big THANKS to PapaArkz for the help as well.

OK here we go:

Make fresh folder on desktop called PixARK (or where ever you want)

In the PixARK folder you just made create 2 folders called steamcmd & server

Make 2 Bat files in the PixARK folder you just made called update.bat & startserver.bat

In the update.bat file put this text -> start "" steamcmd/steamcmd.exe +login anonymous +force_install_dir "E:\PixArk\Server" +app_update 824360 validate +quit

Change the location of your PixARK folder to what yours is.

In the startserver.bat file put this text -> start "" /normal "E:\PixArk\Server\ShooterGame\Binaries\Win64\PixARKServer.exe" CubeWorld_Light?listen?Multihome=192.168.0.100?Port=15000?QueryPort=27019?RCONPort=27020?MaxPlayers=70 -ServerPort=15000 -CubePort=27019 -CULTUREFORCOOKING=en -forcerespawndinos -NoBattlEye -NoHangDetection -nosteamclient -game -server -log -high

Again change the location of your PixARK folder to what yours is. Also change the Multihome IP address to your internal address.

Download SteamCMD unzip it and put the SteamCMD exe into the steamcmd folder.

https://steamcdn-a.akamaihd.net/client/installer/steamcmd.zip

Now double click the update.bat file and let it download the required files.

Next step is to fire up the server so go ahead and double click on the startserver.bat file.

Once the server has finished loading go to PixArk\Server\ShooterGame\Saved\CubeServers\CubeWorld_Light\CubeWorld_Light\

Open up World.ini with a text editor, you can leave the server running.

Make sure that ServerPort is set to 27019

Now you can open/forward ports UDP=15000 & 27019, TCP = 15000 & 27019

Now on your Keyboard hit Winlogo + R and type wf.msc into the box and hit enter

Click on inbound rules

Make Sure that PixARK shows up twice in there, double click each one and make sure that in Protocol and Ports one is set to UDP and one is TCP.

Also on the Advanced Tab make sure that Domain, Private, and Public are all checked off.
And set Edge Traversal to Allow.

Click Apply and exit out of the Firewall Settings.

Stop the server

Now you need to go to the folder PixArk\Server\ShooterGame\Saved\Config\WindowsServer\

Edit your GameUserSettings.ini with a text editor

Make sure this is in there:

[SessionSettings]
SessionName=yourservername
Port=14999
QueryPort=27019
Multihome=same as what you put in the serverstart.bat file

[ServerSettings]
ServerPassword=whateverpasswordyouwant
ServerAdminPassword=whateverpasswordyouwant
RCONEnabled=True
RCONPort=27020
RCONServerGameLogBuffer=600.000000

Restart the server

Now to see your server in the in game browser you need to open Steam up and click view/servers/favorites tab.

Click Add a Server and put in this: 192.168.0.100:27019 (make sure to change 192.168.0.100 to your multihome ip)

Now start up PixArk and you should now see your server under Favorites.

Have fun, and I hope I did not miss anything.

HOW TO UPDATE THE SERVER - Just run update.bat again and it will update your server to the latest version.
