[2020] [Connectivity/Multiplayer]i can not connect to the servers of rainbow when i want to start the match

Hey there TTV-Dan005_cze, I am sorry to hear you've been experiencing this issue! We are currently looking into this error code, but we have a workaround that has helped some players. Please go through the process of unlinking all 3rd party accounts from your Ubisoft account, except for Steam (since you're playing through that client). Start with the Twitch Account first. Then Epic. Please test the game after each unlink, and let me know the results. Thanks!
