Packet signature not matching

[Mufassa4n6]

Hello, I'm following the instructions from pg 221-223 from THB3. However, I am getting the following error message. I tried other payloads and I get a connection but I cannot interact with the shell. Any help or recommendations would be greatly appreciated.
