​​​​​​​​Post-Installation Network and Firewall Access Tests


 

On completing installation of the Cloudamize proxy, if the status of your connection to your vCenter indicates that you are disconnected, you may receive an error message like the one shown in the screen shot below:​

To solve this problem, you must first ensure that the computer on which the proxy is installed has access to both the vCenter and the Internet, by following these troubleshooting steps:

  1. Confirm that the computer on which the proxy is installed has access to your vCenter over the Internet. You can do this using either a Curl command, or by using a Telnet command.

    Note: Neither Curl nor Telnet are installed by default on many Windows versions. To install, see instructions at the following:
  2. Open Command Prompt and issue the following commands to test connectivity using Telnet and Curl commands:
    • Telnet:  telnet 104.197.11.97 443
      • When the screen goes blank, type the escape characters, CTRL + ], and at the prompt, type status.
      • If the connection is successful, you'll receive the message Connected to 104.197.11.97.
    • Curl:  curl.exe 104.197.11.97:443;  if the connection is valid, the command returns SSH-2.0-OpenSSH.
  3. If you are still unable to connect, check that your computer is permitted to send outbound traffic over port 443. Test this to the Destination Google.com using either Telnet or Curl commands.
    • Telnet:  telnet google.com 443
      • When the screen goes blank, type the escape characters, CTRL + ], and at the prompt, type status.
      • If the connection is successful, you'll receive the message Connected to google.com.
    • Curl:  curl.exe google.com:443; if the connection is valid, the command returns the HTML page.
  4. If still unable to connect, check that your network firewall allows outboud traffic on port 443 to the IP address 104.197.11.97.
  5. Wait for at least two minutes, and then refresh the configuration status page by clicking the refresh icon.

  6. If the Curl connection to 104.197.11.97 succeeds, and you still get the disconnected error message, check to ensure that the Agent Proxy is properly installed and functioning by executing the following at the Command Prompt:

    tasklist /svcThe output is a list of running services. Examine the list to locate the following: Cloudamize-Connector.exe, which indicates that the Agent Proxy is installed and running.
  7. If the Agent Proxy is not installed, then reinstall it.
  8. If the Agent Proxy is installed, then check that the proxy is establishing a connection with the Cloudamize servers. At the Command Prompt, enter the following:

    netstat -anotIf there is a valid connection, the command returns the following:

    TCP    <localip>:<localport>    104.197.11.97    ESTABLISHED
  9. If the connection is established, wait at least two minutes, and then refresh the Setup page as in Step #5.
    • If the message on the Status page is changed to "CONNECTED", then the installation is successful.
    • If you get error messages such as "Connection Refused: We notice that you installed the Cloudamize Proxy correctly but we are unable to reach your vCenter," see the Knowledge Base article Troubleshooting Post-Installation Proxy-to-vCenter Accessibility(KB005529) for further instructions.
  10. If at this point you continue to receive connection errors, file a BitTitan support ticket. See How do I get support for your products?​​​
