HTTP Communications Error

If a problem exists with your HTTP configuration, the following error message might be displayed:


HTTP Communications error with Oracle Support Center

Please check your HTTP settings and retry your request.

There can be one or more reasons that this error message is displayed. To troubleshoot the problem, follow these steps:

  1. Verify that your HTTP configuration is correct by typing the following command:


    # regadm list

  2. If your configuration is correct, check the following information:

    • Does your system have access to the public Internet, either directly or through an HTTP proxy? If not, you cannot use the regadm command to administer the Auto Registration feature.

    • Is an HTTP proxy required at your site? If so, ensure that the HTTP proxy host and port have been configured correctly. For instructions, see How to Configure HTTP Proxy and Port Settings.

    • Is authenticated proxy access required at your site? If so, verify that the proxy user name and password have been configured and typed correctly. For instructions, see How to Configure HTTP Proxy Authentication Settings.

  3. Ensure that your HTTP proxy host setting can be resolved to a valid web proxy host that is up and running and has a name that is resolvable.

    For example, if your configured HTTP proxy host is webproxy.example.com, it should be both resolvable and able to respond to a request from the ping utility, as follows:


    # getent hosts webproxy.example.com
192.168.1.1 webproxy.example.com
# ping webproxy.example.com
webproxy.example.com is alive

    For more information, see the getent(1M) and ping(1M) man pages.

  4. If the previous troubleshooting steps do not work, verify your settings with your site administrator.
