Packet captures of working and non-working TLS flows.
Build Information:
Sorry, I aleady upgraded to 1.99.8 (legacy) so I do not have the specific
version info. The problem was seen in v1.12.4 (64-bit); v1.12.6 (64-bit); and
v1.12.7 (64-bit).

Hello Wireshark,
Our company has intermittent TLS issues and we have captures of good and bad
flows. Wireshark v1.12.x shows the good flows with "tcp reassembled in PDU" and
the server certificate. However, the bad flows do not show tcp reassembled and
no server certificate. Using v1.99.8 shows the packets differently as well as
older versions like v1.2.4.
Attached is a packet capture showing the working and non-working flows. Frames
#1-27 are working and frames #28-43 are not working. Please compare frame #7
with #34.
Here are the difference seen with v1.12.x:

Yes, I notice the DSCP differences in the Server Hellos but I cannot say if
this is related to the TLS handshake problem.
Please let me know if more information is needed.
Thank you,
