Connections issue

Hi, I have just gotten a new connection partner for BRI from my Prague. I tell him my nickname and he types it in and it says I have a connection already. I don’t have a connection to BRI, but when I type in his name it works and we have a connection. This might be because I have the same name as somebody or something else. If I’m being dumb and I’m not doing something pls lmk. Thx
