If applicable, add a packet capture to help explain your problem.

### Additional context
Space for additional context, investigative results, suspected issue.

Start with the reported check_rdp function in /home/py/pwd-cracknode/pwd-cracker/src/test/rdp.py, especially line 408 where tls.do_handshake() raises OpenSSL.SSL.WantReadError. Reproduce the failure with the stated Python, target OS, and impacket versions, then determine whether the handshake failure is actionable in the reported code path; the issue is done when the cause and expected handling are established.
