Have you restarted your system? that your using to host the server if that don't work try switching your router on and off , then try to see if your new ip works, if not its either your port is not forwarded or your set up is wrong. sometime anti virus tend to block ports or programs so also try adding samp server.exe and the samp.exe to your trusted programs list on you anti virus program and also if non of the things to i said to try then in Knowledge yes you are black listed.

Sorry for my bad English BTW
