Rafael,  The error of "Error downloading [URL] Make sure that the URL is reachable then logout/login to force another download. java.net.ConnectException: Connection refused" indicates an inability to connect from the vCenter VM to 10.62.36.3, on port 65101.  To verify this, log into the vCenter appliance either via SSH or the vSphere console and run the following command: "curl -k [URL] > tmp.plugin". It should download a .zip of the plugin.  If the vCenter server is running Windows, then browse to the URL [URL] in Internet Explorer. It should download a .zip of the plugin.  This will attempt to pull the plugin file from the Windows host running the install script, as that's exactly what the installation tries to do.  If this test fails, you'll know that the vCenter box can't reach port 65101 and you will need to check firewalls, etc, until it succeeds.  Once this test succeeds, the plugin install should also work.
Hello!!  We are trying to deploy a ScaleIO environment but the plugin registration is not working. Inside PowerCLI the scripts says it worked but loging back on the web client the SIO ScaleIO icon never shows up.  Inside virgo logs I see these mesages:  Error downloading [URL] Make sure that the URL is reachable then logout/login to force another download. java.net.ConnectException: Connection refused     at java.net.PlainSocketImpl.socketConnect(Native Method)     at java.net.AbstractPlainSocketImpl.doConnect(Unknown Source)     at java.net.AbstractPlainSocketImpl.connectToAddress(Unknown Source)     at java.net.AbstractPlainSocketImpl.connect(Unknown Source)     at java.net.SocksSocketImpl.connect(Unknown Source)     at java.net.Socket.connect(Unknown Source)     at sun.security.ssl.SSLSocketImpl.connect(Unknown Source)     at sun.net.NetworkClient.doConnect(Unknown Source)     at sun.net.www.http.HttpClient.openServer(Unknown Source)     at sun.net.www.http.HttpClient.openServer(Unknown Source)     at sun.net.www.protocol.https.HttpsClient.

The behaviour is always the same. The script says it's ok but the icon never shows up.  I can ping the vCenter. vCenter can ping my laptop. On my laptop (while the script is running) if I browse to [URL] my brower downloads EMC-ScaleIO-vSphere-web-plugin-1.32.1440.3.zip immediately. There are no firewalls in between vcenter and my laptop. They are on the same VLAN/Network. I tryed restarting vCenter multiple times but it didn't do anything.  The odd thing is that after the script finishes the registration, If I connect to vCenter using vsphere client, on the plugins menu I see the scaleio plugin but with a message saying "No client side download is needed for this plug-in". But on the web client the icon never shows up. And as far as I know we can't go on with the deploy without this icon on web client.  Any ideas why this is not working?   Thanks! Rafael Bianco
