Connection Loss with Update Manager Server or vCenter Server in a Single vCenter Server System

Because of loss of network connectivity or the restart of the servers, the connection between the Update Manager plug-in and the Update Manager server or vCenter Server system might get interrupted.

Problem

The connection between the Update Manager Client plug-in and the Update Manager server or vCenter Server system is interrupted, when the servers are restarting or are stopped. In such a case various symptoms are observed.

• Update Manager Client plug-in displays a reconnection dialog, and after 15-20 seconds, a failure message appears. The plug-in is disabled.
• Update Manager Client plug-in displays a reconnection dialog. Within 15-20 seconds, the dialog disappears, and the Client plug-in can be used.
• vSphere Client displays a reconnection dialog. After an interval, it displays the login form.

Cause

• The Update Manager server stops and is not available for more than 15-20 seconds.
• The Update Manager server restarts, and the service becomes available within 15-20 seconds.
• vCenter Server stops.

Solution

• If the Update Manager server has stopped, start the Update Manager service and re-enable the Update Manager Client plug-in.
• If the Update Manager server has restarted, wait for it to become available.
• If the vCenter Server service has stopped, start the vCenter Server service and enable the Update Manager Client plug-in.
