Hello,
Please check the below link:
When experiencing SSL handshake failures issues, you can use the following troubleshooting steps to determine the root cause:
- Identifying SSL handshake failures
- Enabling SSL debug logging
- Testing SSL connections (using s_client)
- Reviewing log messages related to SSL handshake failures
- Packet tracing using the ssldump utility

Lots of good advice, specially the whole list from Mohamed_Salah_
There is a good chance you have quite some of them, where it is the other side (the client) which causes them. Make sure you focus on the ones you see a lot or able to solve with the client side. Also keep in mind with an internet connected ADC you will see lots of bots and scans which trigger these.

COMPLETELY AGREE. This is something to chase if its part of an active troubleshooting process where you following a known source. Odds are this is either on the internet OR being monitored /probed by a tool that is not correctly setup. I get thousands of these per day. I chased them once with the links provided by Mohamed - and not a one of my finding came back to real traffic flows.

capture the tcpdump and open the result in wireshark.
the detail of ssl/tls session setup can be easily seen in wireshark
