Virtual Storage Console 4.x stops working after vCenter 5.5U3b update

A Virtual Storage Console (VSC)/SMVI 4.2.2 backup stops working with the following error:

Backups not listing HTTP 504: Gateway Timeout

Unable to backup systems from within VCenter.

  • Clicking the Backup and recovery Configuration option in the VSC plugin in VCenter displays an unable to connect to virtual storage console error
  • Running smvi backup list and other SMVI commands from the VSC server displays an error, and throws java exceptions about handshake failures and a connection been closed in the logs.

Specific issue (identified using Wireshark):

  • After the TCP three-way handshake, VSC by default sends an SSL client hello handshake proposing SSLv3 (0x0300) to vCenter.
  • vCenter then FIN, ACK the connection immediately, causing VSC to issue a fatal alert handshake failure packet back to vCenter, and the client programs to fail/error out. Forcing the client-initiated connections to negotiate at TLSv1 will resolve the issue.
