COD WW2 Cannot Connect to Host Fix: How to Join Your Friends

CoD WW2 is still struggling from online teething issues. After problems with various error codes around its launch day, along with its Headquarters social hub being empty and its Commend system not working, now players are facing a problem that sees them being confronted with a "cannot connect to host" message when trying to play with their friends.

This problem seems to be affecting a significant portion of CoD WW2's player base, with Activision having yet to roll out a fix for it and many players still finding themselves unable to party up with those on their friends list. However, there are some measures that can be taken in an effort to ensure that this error no longer displays, and while they aren't guaranteed solutions, they're the best chance CoD WW2 players currently have of being able to team up with their friends if they're confronted by the cannot connect to host error.

CoD WW2 Cannot Connect to Cost / Unable to Connect to Host Fix: Hard Reset

The first and most simple solution to the cannot connect to host error is to perform a hard reset on your console and router. To do this, hold down the power button on your PS4 / Xbox One until the console turns off completely, unplug it and then do the same with your router. After 10 - 15 minutes, turn all systems back on and see if the issue has persisted.

While a hard reset may not be the solution to your issue, it's best to start off here as it's a common fix to many similar issues, and could well solve your problem before you embark upon more elaborate fixes.

CoD WW2 Cannot Connect to Cost / Unable to Connect to Host Fix: Change Your NAT to Open

You may find that your issues with inviting your friends stem from your NAT type being set to strict, with an open NAT being preferable. To change your NAT type, you will first need to know the IP address on your PS4 and Xbox One.

PS4 find IP address

  1. Go to Settings
  2. Go to Network
  3. Go to View Connect Status
  4. Make note of the numbers listed next to IP Address

Xbox One find IP address

  1. Go to Settings
  2. Go to Network
  3. Make note of the numbers listed next to IP address

PC find IP address

  1. Enter Command Prompt (type cmd into the search bar in Windows 10)
  2. Type inconfig next to C:\users\your user profile
  3. Copy IPv4 Address

You'll then need to take note of the following ports to forward for each platform:

CoD WW2 PC Ports to ForwardTCP: 3074, 27015-27030, 27036-27037 UDP: 3074, 4380, 27000-27031, 27036

CoD WW2 Xbox One Ports to ForwardTCP: 53, 80, 3074 UDP: 53, 88, 500, 3074, 3544, 4500

CoD WW2 PS4 Ports to ForwardTCP: 80, 443, 3074, 3478-3480 UDP: 3074, 3478-3479

How to change your NAT to open

  • Go to your file explorer
  • Go to Network
  • Right-click on your router located beneath Network Infrastructure
  • Go to Settings
  • Write a name beneath Description of service (e.g. COD WW2)
  • Write the IP address found on your PS4 / Xbox One / PC
  • In both External Port and Internal Port, write each TCP number including in the above Ports to Forward section (for instance, on PS4 write 80 in both Internal and External Port, then click OK. Repeat this step until every TCP code has been entered.)
  • After each TCP number has been entered, change the selection to UDP and do the same for these numbers, entering each number twice.

This should set your NAT type to open, and should allow you to navigate around the connect to host error.
