Finding Remote Sessions with Advanced Session Plugin in Host Game System

Hello, I’m currently working on a game using the Advanced Session Plugin in Unreal Engine. While the processes of creating, finding, and joining sessions work seamlessly within the editor, issues arise when packaging the game and sending it to a friend remotely. It appears that they are unable to find the sessions. I suspect this might be due to not being on the same network, although I’m not entirely certain. Now, I’m seeking guidance on how to successfully discover sessions created by my friend remotely.
