Hello,
Thanks for using the PingPlotter forums!
What you want to do (for PingPlotter version 5) is go into the engine settings. You can get there by going to "Edit" -> "Options" and under "Default Settings", choose "Engine". Once there, click the Packet Type dropdown menu and choose "TCP Packets (ie: HTTP, etc). Then under TCP Engine Settings, change the TCP Port to "Other" and input 443. Go ahead an click "OK".
Now, when you enter a target to trace to, you will be tracing using TCP packets on port 443.
I hope this helps. If you need any other help with this or anything else, feel free to email us at any time at support@pingplotter.com.
Cheers!
