Can't connect with the AI companion, any ideas why?

Hey, so I have this project that I'm working on and I'm making an app for it here, but when I try to connect it to my phone using the AI companion, it won't connect. I scan the code and everything, but then it won't load and then it just says that it can connect. Someone please help me.
