I asked to the support. Here the answer, which didn't work for me : Perform a Teredo Reset (Advanced, for PC Game Pass): If you are on a PC, press the Windows Key + X, select Command Prompt (Admin), and run netsh interface Teredo show state . If it shows an error (like "offline" or "restricted"), run this command to reset it: netsh interface Teredo set state type=client . Restart your PC immediately after running the command. Perform a Full Hard Power Cycle (Recommended, for Console): If you are on an Xbox console, press and hold the power button on the front of the console for 10 full seconds until it completely shuts down. Unplug the console from the wall for two minutes to fully clear the network card's internal cache. Plug it back in and restart. Have the Host Reset the Session: Ask your friend (the host) to successfully load the save file in Single Player first, run around for 30 seconds, save the game, close the game completely, and then relaunch it to Host Multiplayer. This clears any corrupt session ID attached to the world. Reset Your Network Stack: Open Command Prompt (Admin) and execute the following two commands consecutively to clear stale network lookup data: ipconfig /flushdns and netsh winsock reset . Restart your computer immediately after running both. We're 2 and play on PC, game bought on Steam recently. First sessions were successful but suddenly it didn't work. Waiting for news from them.
