- 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 in the CAS Registry BLAST window.
Example error messages are
- Logon Failed ("Unknown Host Exception("<hostname>")")
- Logon Failed ("IOException: "Unable to tunnel through <proxy>:8080. Proxy returns "HTTP/1.1 407 Proxy Authentication Required""").
- Logon Failed ("Socket Exception("network subsystem has failed: connect")").
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.
Use the information from this step to change preferences, as shown below..
Step B: Configure CAS Registry BLAST
- In the STN Express main menu bar, click Setup,
- then Preferences,
- then STN Online and Results.
Step C
- Click the BLAST tab.
- Select the type of firewall / proxy server being used, HTTP (including HTTPS or Secure) or SOCKS. Note: SOCKS 5 authentication is not supported. SOCKS 4 or SOCKS 5 without authentication should work.
- Type the proxy server's host-name or IP address.
- Type the proxy server's communication port number.
- Click OK to close the Preferences dialog and save the settings.
After changing the BLAST proxy server preferences, try again to log in.
