NimbostratusSSL Handshake failure
Hello, I need help with one situation.
We have one application behind F5. We are terminating SSL on F5. When we access application through normal web browser we get desired output. But when we try the same application with SoapUI we do not get the output.
we tried to debug and packet capture and we found that SSL handshake failure causes the issue. with my limited knowledge I tried to extract ssldump and output shows that ssl failure occurred, but i am not able to find out the reason for the same.
below you can find the output of ssldump: please let me know if you have any suggestion to troubleshoot the issue further:

The odd thing is that you're actually completing the SSL handshake (it's the application_data messages). And it looks like you're doing mutual (client certificate) authentication successfully.
Since you're doing an RSA handshake, you should be able to put the server's private key into the SSLDUMP and attempt to decrypt.
ssldump -AdNn -i [interface] -k [path to private key] port 443 [and additional filters]There's something happening just after the handshake that's causing the issue, so it'll help to see the decrypted payload.

Is that SoapUI access is FQDN? If yes do you have SSL trusted root CA loaded in the client machine where the soap calls running from?
