Configuring Collaborate with your Proxy Settings

Step 1: Begin the process of connecting to  your Collaborate session.  You should eventually receive a 'Connection Failed' error similar to the one below.  Click on Cancel.

Step 2: In the Collaborate window, click on Edit and then Preferences...

Step 3:  In the Preferences window, select Proxy Settings in the left hand side.  Then on the right hand side, set Method to HTTP Proxy Server.  The server and Port should autofill with your proxy information.  If it does not, see Verifying Your Proxy Settings below.

Step 4: Click on Apply and then OK to close the Preferences Window.

Step 5: Try reconnecting to the session by clicking on Session and then Join Session

You should now be joined to the session.  This should only have to be done once per computer and user account. 

If you are still unable to connect, try an https connection.

Go back to the Collaborate Preferences window (Edit > Preferences), select Proxy Settings in the left hand side.  Then on the right hand side, set Method to HTTPS Proxy Server. The server and Port should autofill. If it does not go to Verifying Your Proxy Settings below.

Click on Apply and then OK to close the Preferences. Now try reconnecting to the session by clicking on Session and then Join Session.

You should have successfully joined the session.  This should only have to be done once per computer and user account. 

If you are still unable to connect, please contact NPS Support at 831-656-1046, DSN 756-1046 or at tac@nps.edu.

Explanation of the various Proxy Setting options are:

  • Proxy Settings From Launcher – Specifies that Collaborate is to use the connection settings from Java Web Start. If manual proxy settings are not provided to Java Web Start, it will attempt to detect these settings on its own and then pass the results to Collaborate. This is the default proxy setting and should be changed only if you are unable to establish a reliable connection.
  • Direct Connection – Specifies that no proxy server is to be used. Collaborate will connect directly to the appropriate server.
  • Use SOCKS V4/V5 Proxy Server – Specifies that a version 4 SOCKS proxy server is to be used.
  • HTTPS Proxy Server – Specifies that a secure HTTPS proxy server is to be used.
  • HTTP Proxy Server – Specifies that an HTTP proxy server is to be used.
  • HTTP Proxy Server (Half-Duplex) – Specifies that an HTTP proxy server is to be used in reduced bandwidth half duplex mode. Use this option only if you have an HTTP proxy server and you are unable to establish a reliable connection with the previous setting.
  • HTTP Direct – Specifies that Collaborate is to connect directly to the server with the HTTP protocol. While this is similar to a direct connection, the use of the HTTP protocol may reduce performance and should be used only if a normal direct connection is not possible.
  • HTTP Direct (Half-Duplex) – Specifies that Collaborate is to connect directly to the server with the HTTP protocol in a reduced bandwidth half duplex mode. Use this option only if you require an HTTP direct connection and are unable to establish a reliable connection with the previous setting.
