Symptoms

The error appears while opening Console option in CCP for OACI subscription:

Network Error: Unrecognized SSL message, plaintext connection?

Also, there can be the following error:

Network Error: Connection has been shutdown.

Cause

SSL certificate is broken in dispatcher on a certain hardware node.

Resolution

  1. If OA version is greater than 6.0.8, but the Java console is used, download the utility from here and copy it to /usr/local/pem/bin/

  2. Generate new certificate on with:

    # /usr/local/pem/bin/mkselfsignedcert
    Generating a 2048 bit RSA private key
    ..................+++
    .................................................................................+++
    writing new private key to '/tmp/mkssc.799155.key'
    

    Note: the utility applies newly generated certificate automatically.

  3. Go to CCP and click the Reset console button.
