Hello HippedOak0608, I have moved your post to its own thread as you were commenting on the wrong issue and your issue id that you receive the 8-0x00001300 error code in game.
I have checked your case number and can see you were asked to provide a screenshot of your port forwarding. Please update your case through our Ubisoft Support website with this information when you can, as we need this information to be able to help you troubleshoot this error code further, thank you.
