Symptoms

  • Cannot connect to the View Connection server that is behind a firewall
  • Connecting to the View Connection server that is behind a firewall fails
  • You see the error:

    The View Connection Server authentication failed. A secure connection to the server '(null)' cannot be established.

Cause

The View Connection server is configured to use the Secure Tunnel connection to the desktop. This requires that the firewall allow port 443 to be open. If the firewall does not allow communication on port 443, the connection between the Client and Connection Server cannot be established.

The same error may also be displayed if an invalid port is defined in the External URL.

Resolution

To resolve this issue
  1. Check the External URL configuration for errors
  2. Check DNS for proper name resolution
  3. Check firewall configuration.  Open ports on the firewall to allow communication between the Client and Connection server. Port 80 and 443 are used to connect Client and Connection servers. For a complete list of ports used in VMware View, see:
