After an upgrade of the UVMS Master and Subordinates, the communication of the UVMS Product Version is only done in one direction (Subordinate to Master).
The master does not send his version to the Subordinates.
As a result, the old version of the Master UVMS is displayed in the list of Nodes in UVC.
Univiewer Management Server 6 in Advanced Architecture ( Master / Subordinate)
Update to a fix version listed below or a newer version if available.
Component: Univiewer.Management.Server 6.9.61
Released 15th January 2019
To resolve this issue, the setting "Enable check of status for Master" has been added in the Node Settings of the Univiewer Server.
Set this value to 'Yes' in the Subordinates UVMS.
