I am running FSD 3 Rev 775, Dashlaunch 310 (535) and I have Devlink (disabled), ping patch (enabled) and Contpatch is set to (off), I also ensure that I have the latest TU for any game I want to use on Link, I have tried to enter system link with the FSD plugin (enabled and disabled) but neither help. This is a Dual Nand console. I have run the test in FSD and it's all clear with my ports open and upnp enabled, I can get into the system link menu from the home button and enter lobby rooms, I can even go go back to the game open system link and see the lobby I have joined, but thats as far as I can go as when I click to connect to the game I always get an error message, strangely I can create rooms where others can join fine. I really did try to research this but I could not find a solution. Does anyone have any ideas where I might be going wrong? Many thanks!!!
