I set my port in my minecraft server to be opened and nothing changed. Server is running and the port is binded corectly: "Server started at port 24454". When i join, there is crossed plug sign, and info about no connection. I used the netcat (only on the server, i cant open it up on client idk why, its crashing after puting the line in), and on server it worked, i got text back. What do i do then?

also on the opened port tool i checked if it opened, It is.
