Troubleshoot Access to the Hosted WMS Database

wmsfind can search a version of the WMS database hosted on the MathWorks® website. The information found in the web-hosted database is updated regularly.

If your network uses a firewall or another method of protection that restricts Internet access, provide information about your proxy server to MATLAB®. Be aware that:

  • MATLAB supports non-authenticated, basic, digest, and NTLM proxy authentication types.

  • You cannot specify the proxy server settings using a script.

  • There is no automated way to provide the proxy server settings your system browser uses to MATLAB.

To specify the proxy server settings:

  1. On the Home tab, in the Environment section, click Preferences. Select MATLAB > Web.

  2. Select the Use a proxy server to connect to the Internet check box.

  3. Specify values for Proxy host and Proxy port. Examples of acceptable formats for the host are: 172.16.10.8 and ourproxy. For the port, enter an integer only, such as 22. If you do not know the values for your proxy server, ask your system or network administrator for the information. If your proxy server requires a user name and password, select the Use a proxy with authentication check box. Then enter your proxy user name and password. MATLAB stores the password without encryption in your matlab.prf file.

  4. Ensure that your settings work by clicking the Test connection button. MATLAB attempts to connect to https://www.mathworks.com. If MATLAB can access the Internet, Success! appears next to the button. If MATLAB cannot access the Internet, Failed! appears next to the button. Correct the values you entered and try again. If you still cannot connect, try using the values you used when you authenticated your MATLAB license.

  5. Click OK to accept the changes.

On Windows®, if no proxy is specified in MATLAB preferences, wmsfind uses the proxy set in the Windows system preferences. To specify system proxy server settings, refer to your Windows documentation for locating Internet Options. On the Connections tab, select LAN settings. The proxy settings are in the Proxy server section. MATLAB does not take into account proxy exceptions which you configure in Windows. Even if you have specified the correct credentials in the MATLAB preference panel or in the Windows system proxy settings, the wmsfind function returns the error Proxy Authentication Required if the proxy server in MATLAB preferences requires an authentication method other than Basic. The proxy server in Windows system preferences requires authentication of any type.
