Divinity Original Sin 2 – Error Connection Failed

After investigating this particular issue thoroughly, it turns out that there are several different scenarios that might be triggering this error code. Here’s a list of potential culprits:

  • Game Version Mismatch – As it turns out, you can expect to see this error code if you’re trying to play a co-op game with a buddy that has a different version of Divinity Original Sin 2 than you. In this case, you can resolve the issue by ensuring both of you are running the same game’s version.
  • Corrupted Windows 10 profile – According to some affected users, you can expect to see this error pop-up appearing if you’re trying to open the game while signed in with a corrupted Windows 10 profile. In this case, you can resolve the problem by creating & using a new Windows 10 profile while opening the game.

  • Divinity: Original Sin Blocked Ports – Under certain circumstances, you can see this error popping up because some ports that the game needs to access in order to facilitate cooperative gameplay are not opened. In this case, you can resolve the issue by enabling UPnP or open the necessary ports manually.

Method 5: Open Divinity: Original Sin 2’s Ports

If none of the methods above have been effective in your case, you should consider that this particular issue might be related to a game port that is not opened on the network that you’re currently connected to.

If this scenario is applicable, you can ensure that the ports used by Divinity: Original Sin 2 are all opened by enabling UPnP (Universal Plug and Play) if your router supports it or by forwarding the used ports manually if you’re using an older router.

Note: Regardless of the method that you’ll end up going for, it needs to be done on both your PC and your friends’ PC if you’re playing cooperatively.

A. Enabling UPnP

Keep in mind that nowadays, the vast majority of routers are automatically capable of forwarding the ports used by the game you’re actively playing with a feature called UPnP (Universal Plug and Play). 

So unless you modified the settings on your router, this UPnP feature should be enabled by default. However, if you made some changes yourself, here are some instructions on enabling UPnP in your router settings.

In case UPnP is not supported by your router, follow the instructions below to forward the ports manually.

B. Forwarding the game’s ports manually

  1. Start by opening your default browser and type one of the following addresses and press Enter to open your router settings:
  2. Once you’re at the initial login screen, enter the login credentials to access your router settings.
    Accessing the Router settings

    Note: Keep in mind that in most cases, you’ll be able to get in with the default login credentials – admin as username and 1234 as password. If these generic credentials don’t work, search online for the default login credentials of your router model.

  3. After you have successfully arrived inside your router settings, expand the Advanced / Expert menu, and look for an option named Port Forwarding / NAT Forwarding.
    Forwarding the necessary ports
  4. Next, go ahead and manually open the ports below to ensure that your network will accept incoming connections from the Divinity: Original Sin 2:
    23243 - 23252
    23253 - 23262
  5. Once every port is successfully forwarded, restart your computer, launch the game once again and see if the problem is now fixed.
