Issue with connecting

So I have a beammp server set to private and its authenticated and is good, my ISP allows the port thru when the server is running,
image

and my windows defender is allowing it also, I just cant figure out why no one else can connect.

What issues are people having when connecting?
What errors do they get?
Did you port forward on TCP and UDP?
IF you are using xfinity, you will have to disable the security feature for port forwarding to work.
