Is there an error displayed in the client's browser?

 

We encountered the issue when upgrading from v11.2 to v11.4.1, pertaining to SSL/TLS ciphers. The client's browser said something about enabling TLS, and changing the server SSL profile cipher string to 'DEFAULT:!TLSv1_1:!TLSv1_2' was our fix.

 

If SSL renegotiation is your issue, then in /var/log/ltm you should see a message indicating that.
