SSL connection warning is reported after installing or upgrading to vCloud Director 5.5 (2060063)

  • 1 Ratings


  • You see an SSL connection warning after installing or upgrading to vCloud Director 5.5
  • You see the warning:

    Warning: The specified keystore contains a DSA key which has been found to cause intermittent SSL connection failures; see KB 2056026 for details.


To minimize the likelihood of an unsuccessful SSL connection, vCloud Director 5.5 is, by default, configured to disallow ciphers that are known to cause SSL connection failures. When you install or upgrade vCloud Director, the installation or upgrade script examines the cell's certificates. If any of the certificates are encrypted using one of the disallowed ciphers, the script modifies the default configuration to allow use of that cipher and displays this warning.


This is a known issue affecting VMware vCloud Director 5.5.x.

To workaround this issue, use the cell management tool to replace the cell's existing certificates with certificates that do not use a DSA-based cipher and then reconfigure the cell's list of allowed ciphers to disallow use of DSA-based ciphers.
