Problem:

  • After the installation of the Cloudamize proxy, the status of the connection to your vCenter is "DISCONNECTED" with a message such as:

    • "Connection Refused: Please make sure that you installed the Cloudamize Proxy correctly. The Proxy should be installed on a machine that has access to the Vcenter as well as to the internet."
    • Alternatively: "UnknownException: An unknown error was encountered using the information entered. Please check the information that you provided and contact helpdesk@cloudamize.com for further assistance".

Solution:

  • The machine where the Cloudamize Proxy is installed needs to have access to the internet and to your vCenter machine. 

    • Check that your machine is permitted to send outbound traffic to Cloudamize servers on port 443:

      Using Curl:

      command:
      curl.exe 52.202.114.20:443
      output:
      SSH-2.0-OpenSSH

      Using Telnet:

      telnet 52.202.114.20 443
        
        
        


       

    • If unable to connect please check that your machine is permitted to send outbound traffic to google.com on port 443:

      Using Curl:

      command:
      curl.exe google.com:443
      output:
      <HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
      .....

      Using Telnet

      telnet google.com 443
        
        
        
    • If unable to connect please check that your network firewall allows outbound traffic on port 443 to IP 52.202.114.20. 
    • Please wait 2 minutes and refresh your configuration on the Cloudamize Setup page:
  • If the curl connection to 52.202.114.20 succeeds and you are still getting the same error message, please check that the Cloudamize Proxy is installed and working properly.

    • Check that the Proxy is running:

      Command:
      tasklist /svc
      output:
      Cloudamize-Connector.exe      <pid> Cloudamize-Connector

    • If you do not see the Proxy installed then please re-install the previously downloaded proxy.

    • Check that the connection is established with the Cloudamize servers

      Command:
      netstat -anot
      output:
      TCP    <localip>:<localport>       52.202.114.20:443      ESTABLISHED
  • If the connection is established, please wait 2 minutes and refresh your configuration on the Cloudamize Setup page:
    • If the error message on the Cloudamize connection status page has changed to "CONNECTED" then the installation is successful. 
    • If you notice that you are getting a different error such as "Connection Refused: We notice that you installed the Cloudamize Proxy correctly but we are unable to reach your vCenter", please go to Post-Installation Proxy to vCenter Accessibility for direction on how to solve that problem. 
    • If the error message remains the same "Connection Refused: Please make sure that you installed the Cloudamize Proxy correctly."
  • After going through these steps, please contact helpdesk@cloudamize.com with the results of the above tests and the log.txt file located in either C:\Program Files (x86)\CloudamizeProxy or C:\Program Files\CloudamizeProxy.
