VNC console doesn't work for Virtual Machines in PVA, if it is accessed by its FQDN, for example, https://pva.pcs.test:4648.

The console works correctly, if PVA is accessed by its IP address.

With enabled Java tracing it produces the following errors :

network: Cache entry not found [url: https://pva.pcs.test:4648/vz/rdp/VncViewer.jar, version: null]
network: Connecting https://pva.pcs.test:4648/vz/rdp/VncViewer.jar with proxy=DIRECT
network: Connecting http://pva.pcs.test:4648/ with proxy=DIRECT
... handshake alert:  unrecognized_name
java.lang.ClassNotFoundException: com.tightvnc.vncviewer.VncViewer


An SSL handshake alert occurs, if the referenced hostname doesn't match the one, defined in Apache configuration on the PVA MN server.

Oracle Java bug reference:

Java Runtime Environment versions 7 and 8 are affected by the problem.


Add ServerName directive to /etc/httpd/conf.d/ssl.conf file on PVA MN that will be mapped to the FQDN and port 4648.


[root@pva ~]# grep ServerName /etc/httpd/conf.d/ssl.conf
# #ServerName
ServerName pva.pcs.test:4648
