Bug Name Multiplayer

The problem is that when the player enters and takes his name, it does not appear to the other player
The code I used

Use Mirror:

[SyncVar(hook = nameof(SetColor))]
public string name;
public TMP_Text nametext;
void SetColor(string _, string newColor)
{
userFName = name;

nametext = GetComponentInChildren<TMP_Text>();
nametext.text = newColor;

}
public override void OnStartServer()
{
base.OnStartServer();
userFName = MssqlConnection.user.userLName;
Debug.Log(name);
nametext.text = userFName;
}
