Alert 20 is a generic error. Two options:

  • Uncheck "Generic Alert" in the client SSL profile and inspect the logs again. This may be enough to produce more detailed error messages.

  • Perform an SSLdump on whichever side of the F5 you think the SSL errors are happening:

    ssldump -AdNn -i [vlan] port 443 [and any other filters]

In many cases an SSLdump will at least tell you where the issue is happening if it happens in the TLS handshake.
