--- Comment #14 from Michael Carpino <mfcarpino at gmail.com> ---
What I can share at this point is based on the information I've been able to
obtain thru the use of Wireshark and a Wireshark expert (Chris Greer) that's
been willing to assist me with my issue.

The problem for me seems to start in the communication from the client (my
Computer). It sends out information telling the server that it supports the
different version of Transport Layer Security (TLS).  My computer (Fedora OS)
tells Yahoo that it has available versions, 1.0, 1.1, 1.2 and 1.3.  Yahoo comes
back and tells my computer that it wants to use version 1.3. All of this
happens extremely fast within the initial communication between them.  It's
less than a second and it's actually a small portion of a second.

Here's where we think the problem is.  Within that same (Hello) exchange when
it tells my computer it wants to use version 1.3 it later says in the same
message to change the cipher spec protocol to v 1.2 and the application data
protocol to v 1.2.   Now keep in mind this is all happening within a portion of
a second.

Then for some unknown reason my computer stalls (I believe within the OS) and
it this point we think it's trying to figure out what to do with the
conflicting information.  Then at around 48-49 seconds later it sends what it
needs back to Yahoo and boom I get the updated stock price.   

That's where things are right now as far as what we know about my issue.
