In this video we'll be covering how to troubleshoot some common TLS handshake problems using Wireshark. We'll review what a healthy handshake looks like, then dive into three failure scenarios:

1 - The target server is not running TLS on the specified port
2 - The target server does not accept the client's TLS version or cipher list
3 - The client does not accept the server's TLS certificate
