Cannot View Console Window Content on VMWare vCloud Director i.e. WebMKSConsole.html

Andy Diwaniyan
Andy Diwaniyan used Ask the Experts™
VMWare Client Integration Plugin v6.2 (For Internet Explorer 11 and Firefox Ver. 66)
VMWare Client Integration Pluginv6.0 (For Google Chrome Version 73.0.3683.103 (Official Build) (64-bit))
on a
Windows 7 Enterprise SP1 (64-bit) PC.

What Works
- ISO upload to VMWare vCloud Director Catalog works using Internet Explorer 11 only (does not work with Chrome and Firefox) on the PC.

Workaround in place - Console Content Access works for all the same VMs via a Windows Server 2008 R2 Standard Server from within the same environment (setup by someone else not contactable)
(This Server will be decommissioned soon - so need the console working on the PC before the server gets decommissioned)

What Does not work
– VMWare vCloud Director WebMKSConsole Content Access – for any VMs – using any Web Browser (IE, Firefox or Chrome)

Get the following screen – doesn’t matter whether the URL is DNS Name or via IP Address.

Troubleshooting done
-      Added DNS Name to local host file on PC (which made the ISO upload work)
-      Reinstalled VMWare Client Integration Plugin v6.2 , v6.0 and v5.6 after uninstalling, reinstalling and rebooting a number of times.
-      Added Firewall Exclusions on Local PC for all profiles (Domain, Private and Public)
-      Installed the Valid Certificate for FQDN in Automatically Selected Store and the Trusted Root Certificate Store.
-      Tried Troubleshooting described on various VMWare Website and Forums – some were unclear.
-      VMWare Tools on most VMs updated to Version 10305.
-      Have Local Admin Rights to the PC

Need help with location of root cause of problem / log files specific to problem and get the WebMKSConsole.html working on any browser.

Are the browser versions the same as what is installed on the Windows 2008 Server.

We are observing many Web Browsers fails using old GUIs recently, because of Java, WebKit functions which have now been retired in new browsers like Firefox, Chrome and IE.

I would obtain older versions of Firefox and Chrome and try, even if it means building an older OS (e.g. Windows XP or Windows 7)
Pete LongTechnical Consultant

Agree with Andrew, Im my previous post we had to use a 'stand alone' unpatched version of Firefox to access the consoles of our VMs

Thanks Andrew and Pete, have tried going to Firefox Version - not working. However, yet to try a full rebuild to an older OS and older version of Firefox.

As far as the Windows Server 2008 R2 Standard Server is concerned, browser versions are the same Firefox Version 66 and Chrome Version 73 on both the Server and the PC. It works for Firefox and Chrome browsers on the Server.

Will try and move the test PC to the same OU as the server and see if eliminating the group policies helps.

Hi Andrew and Pete,
Thanks for your contribution and appreciate your time.

Thought you might be interested to know what fixed it for me.
VMWare published a VMWare Client Integration Plugin for vCloud Director 8.20 specifically but was at the bottom of the Article (kind of embarrassing for me to discover that).
However, the second bit and the most important fix was that the Remote Console Web URL had a specific DNS name and another IP Address that was allowed through the corporate firewall. When entering this entry into the host file from the PC I was accessing, it worked straight away for Internet Explorer, Google Chrome and Firefox.
It was a lack of IP knowledge which took a while to track down.
