warning tmm3[11615]: 01260013:4: SSL Handshake failed for TCP

Hi Team ,

 

We have an SSL error message on F5 :  warning tmm3[11615]: 01260013:4: SSL Handshake failed for TCP (error from same single source )

We did not find any logs for VIP down or backend server down at the time of above SSL error message .

Can you please advice what could be the issue in this case .

 

VIP :433

Backend server listening on port 8040

SSL-client profile applied (only ssl offloading)

application delivery
BIG-IP
LTM
ssl

    The peer closes the connection before the SSL handshake completes. For more information take tcpdump and see if any unusual behaviour

      Hi Samir ,

       

      This was one time issue between specified time , So except SSL handshake logs we do see any other abnormality .

       

      When you say peer closes the connection , Do you mean F5 << >> Pool member connection ? , In this case also VIP and pool members where not down .

        Its early to comments without seeing tcpdump. Did you capture tcpdump?
