webMethods Knowlegebase : SSL client cannot connect to the SSL server. OpenSSL showcerts error 'sslv3 alert unexpected message' (1734136)

Troubleshooting


Problem

SSL client tries to connect to SSL server. Running the command:

openssl.exe s_client -verify 6 -state -msg -showcerts -connect SSLSERVERNAME:SERVERPORT

Shows output similar to:

>>> TLS 1.0 Handshake [length 00cd], ClientHello

01 00 00 c9 03 01 4e e0 ca a7 80 01 9f ba 04 d7

...

SSL_connect:SSLv2/v3 write client hello A

SSL3 alert read:fatal:unexpected_message

<<< TLS 1.0 Alert [length 0002], fatal unexpected_message

02 0a

SSL_connect:error in SSLv2/v3 read server hello A

5828:error:140773F2:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert unexpected message:.\ssl\s23_clnt.c:658:
