• Did you verify if port 443 is being used by any other application?
• This issue occurs if Port 443 is in use by another application. Routing and Remote access is a common service that may be using Port 443.
• This can also happen if the certificate friendly name is VDM instead of vdm, or if the certificate is not marked as exportable.
• Run netstat –ano
• If port 443 is used by another application, identify the process name of the application and disable the service that corresponds to the process.
• If there is any other SQL monitoring service Or routing-remote access service running on server which requires port 443 or 80, disable that.
• If the issue still persist, stop vmware view web component service > rename installpath\Server\broker\webapps\admin folder to admin_old > Start the service > It will create a new admin folder in this location. Try to access the page now.

• If issue still persist create a locked.properties file once (VMware Knowledge Base ) and see if it helps.

• If issue still persist, check the debug log under %allusersprofile%\VMware\VDM\logs\debug_xxxxx.log.It will tell you the exception when the page is failing.

• Also check if there is any recent windows update has been pushed to connection server. If so, remove the most recent updates and try again.
