Friend Can't join room due to username error

So I’m trying to set up a room for me and my friend and when he tries to join it gives an error message stating that my username is invalid and must be 4-20 Alphanumerical digits. I changed usernames and switched places hosting rooms but it gave the same error nonetheless. We are both running Nightly.

You don’t appear to have set a Username for yourself in the lobby menu. Try setting one that is at least 4 alphanumeric characters long.
