Connecting to CAS Registry BLAST Using STN Express 8.0 with Discover! (Microsoft Windows)

If you are not able to log on to CAS Registry BLAST, or if your computer cannot connect to the BLAST server, an error message appears:

CAS Registry BLAST login error

The problem can often be corrected by setting proxy server preferences in CAS Registry BLAST.


Step A: Determine the Proxy Server

Your IT department or internal help desk is best-equipped to tell you if you should use a proxy server and, if so, which proxy server you should use. However, if your web browser is configured with a proxy server, you can try using the same information in CAS Registry BLAST.

We are interested in these aspects of the proxy server:

  • the proxy server's name or address
  • the proxy server's port
  • whether the proxy server is an HTTP proxy or a SOCKS proxy.

Here's how to check your web browser for proxy server information. The steps may vary somewhat with different browser versions.

  • How to locate proxy information in Microsoft Internet Explorer

Use the information from this step to change preferences, as shown below..

  4. Type the proxy server's communication port number.
  5. Click OK to close the Preferences dialog and save the settings.
