SSL Handshake failed for TCP

Hello

 

I have Exchange 2010 in a load balancing in a guest with version 11.4.1 hotfix 9, the following logs

 

SSL Handshake failed for TCP from 90.28.28.47:62362 to 192.168.125.48:443 SSL Handshake failed for TCP from 90.28.32.61:50526 to 192.168.125.48:443

 

I need to understand this and solve it, I modify a debug in SSL log and I could see a logs

 

Mar 16 10:51:17 slot1/F5ch1g1 debug tmm[10638]: 01260009:7: Connection error: ssl_hs_session:4807: cipher selected does not match original session's cipher (47) Mar 16 10:51:17 slot1/F5ch1g1 info tmm[10638]: 01260013:6: SSL Handshake failed for TCP from 90.27.11.140:51671 to 192.168.125.48:443

 

In this case, How I could solved it? because there are a lot of logs.

    Hi JAIME,

    As per log, It looks like both side SSL certificate(F5 & mail Server) is not correct. Run below command for verifications on f5 & paste output.

        openssl s_client -connect :
