@magge @S_SoulReaver Thank you for your answer. I think i found what was not working. Windows defender was blocking access to folder. I saw a quick pop up but when i went to history of windows defender, nothing was showing up. By reading this post : https://answers.microsoft.com/en-us/protect/forum/all/windows-defender-protection-history-is-missing/627df29d-017f-44f7-9111-99241f9929ae I could make access to folder and after a faf reboot, i was able to join a game. I close the thread but thank for trying to help. Hope it could help others with the links i found. See you ingame, Corwin edit : i dont see where to close thread !
