If the game has kicked you out and shown the 'Lost Connection to Host' error message, there could be a few things that could be causing it.
Solutions for 'Lost Connection to Host' error
Firstly, please make sure that the game is not being blocked by your antivirus software.
If it's not your antivirus, then please check if have any of the following software installed on your PC:
If you do, please press Ctrl+Alt+Del to open Task Manager, find Asus GameFirst VI and Asus Aura on the list, right-click on each and select End Task. Alternatively, you can uninstall the Asus software, reboot your PC and open the game to check if the problem has been resolved.
If the issue continues, then please follow the steps below.
Go to the Windows Settings
Click Network & Internet
Click the link Network and Sharing Centre
Then click on the link you have under the Access Type, next to Connections - the link is the Ethernet cable or WiFi you are using to connect
Go to Properties
Find Internet Protocol Version 6 on the list and uncheck it - if this option is already unchecked then please turn it on, press OK, then turn it off again and press OK
Then please retest your game.
Connect your PC directly to your router with a LAN cable. Don't use any adapters, network extenders etc. If you were already doing this, try to replace the cable if you have a spare one, and retest the game.
Check your currently running processes, especially antiviruses, internet and motherboard utilities. Check their settings to make sure they don't slow down your internet. If nothing improves the situation, close every software you can one by one and retest the game.
