(Help please) Revision Control not working

My brother and I are very new to Unreal Engine and want to work together to make a project. I have figured out how to start the Multi-User server and I’ve made the project the same name and so has he and we’re on the same LAN and my brother connects and I can see his avatar in my project flying around but I cannot see him make changes to the environment, when I go to the bottom right and see Revision Control I try to enable it and it says “Failed to connect to revision control. Check your settings and connection then try again.” I’m confused where to find the settings it refers to and also why it would be saying this when I’ve watched a tutorial online about Multiuser editing in Unreal and followed it exactly and his revision control in the video works right off the bat with no tweaks.
