Troubleshoot TLS Handshake Failures using Wireshark

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

Excellent lesson. Really hope you'll consider doing more. Maybe, analyzing kerberos, LDAP, etc.?

Please make a video on how to identify encrypted tcp packets from unencrypted ones. I am self hosting rustdesk and in wireshark i cannot see tls handshake or anything related to ciphers. All i see is plain tcp packets. But rustdesk says connection is encrypted when i use keys and unencrypted when i dont use keys. how do i actually make sure it is encrypted in wireshark ? Thanks for making great videos
