    Yup. Anything more than a year is silly for several reasons, hence the move to a maximum period of one year by CAs and browsers etc.

    Now we just need to work out how to fix it.

    and that is the problem with long expiry certs. When you need to renew it nobody knows how any more

    If you want to probe the tls on the server, try testssl.sh.

    probably an expired certificate. Or an untrusted one. Can you point a browser at the listening socket and see what the cert is (don't use IE)?

    Turn on debug logging with:

    -Djavax.net.debug=ssl,handshake

    it will give you copious information about where/what is failing in the handshake.

  • Oracle middleware issue - Cannot connect to Node Manager. : General SSLEngine problem

    We're running Oracle Middleware on Windows Server 2012 R2. Oracle version is Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production.

    When trying to run the Middleware via script we're seeing the following error - any ideas? Unfortunately, we no longer have an Oracle support personnel available, hence we're struggling to resolve:
