This is a very common problem and the short answer is: it doesn’t have a solution that I know of. Sorry. :( Read on for additional info & a possible workaround.

Typical features of this problem:

• • Two or more players on the same local network receive the “Latency is too high” message when trying to join each other’s games, even if other people are able to join said games.
  • If they join a game hosted by a third party it will be very laggy and they will usually lag out and drop a few seconds after the game begins.
  • Each person individually can join & play games with other people on the server
  • Sometimes forwarding a different port to each computer will allow players on the same network to join & play in each other’s games — you can doing try this, but it’s doesn’t work a lot of the time.
  • It has been speculated that this problem is specific to certain makes/models of routers, or possibly related to using Windows 10.

Workaround – Using a VPN

The only known solution that will for sure let people with this problem play together is for each additional PC on the network to use a VPN. A VPN will route Internet traffic to a new endpoint and give you a different external IP address which effectively bypasses this problem.

I’ve personally tested ProtonVPN — it’s very easy to set up and is completely free & unlimited. In my test I was able to join and play several matches with zero lag!

How to set it up:

1. Register an acount using the “Free” plan & download the app
2. Run the installer to install the app
3. Double click the desktop icon to launch the app
4. Click on “Quick Connect” to initiate the VPN connection

The app will automatically connect to one of the available servers and show you your new external IP address in a tray notification:

Additional tips:

• One of your PCs should NOT be using ProtonVPN. So if you have two PCs, use it on one of them. If you have three PCs, use it on two, and so on.
• Whichever PC is NOT using ProtonVPN should forward port 6112 if they want to host matches.
• VPN users will not be able to host, but can join & play in any game.
• If you have problems with ProtonVPN another VPN I’ve tested is Tunnelbear. Tunnelbear is also free to use but limited to 500MB of data per month. If you do use Tunnelbear make sure to turn it off when you’re not actively gaming! so you don’t waste data on general Internet browsing.

Unfortunately this isn’t the most convenient solution for everyone, especially when there’s three or more PCs trying to play on the same network, but it’s the best option we have for the time being & should get the job done for the most part.

Good luck!!!
