Having trouble with creation of a cloud service with multiple virtual machines using java sdk.

Question

I am creating a cloud service on azure with 2 virtual machines using java sdk API. Service created successfully.
My input endpoint details are as follows.
INPUT ENDPOINTS
Head : 191.238.144.47:2400
Head : 191.238.144.47:22
Node0 : 191.238.144.47:43211
For Head instance port 2400 is for HTTPS and port 22 is for SSH and for Node0 instance port 43211 is for SSH.
But I am having problem with doing a ssh on Head instance. Sometimes it works sometimes doesn't. Same problem with HTTPS also.
I have some application running over there but when i try to access it thru browser sometimes it works but most of the time doesn't. When I restart the instances from azure portal, its works after
that(not always but most of the time). 
Now I am confused what is going on there. I am creating cloud service and virtual machines using java sdk and setting input endpoints also. After creation of all instances i restart every instance programmatically .
I am not sure whether restart is required or not. It must be something to do with input endpoints only but not able to get the right thing i guess. When i do the same thing thru azure portal(creation of cloud service with virtual machines and setting up input
end points) everything works fine but not achieving the result when implementing it by java sdk API. Please help me.

HI Nithin,
Thanks for your reply. I am setting the endpoints after creating my instances using update call. Here's the code snippet.
AzureService aServ = new AzureService(session);
 if(aServ.checkNameAvailability(clusterName)) {
           aServ.createHostedService(clusterName, "dbX cluster");         
         // Creating head instance
         aServ.createHead(clusterName, imgName, headType, userName, pswd);  
        // Setting end points for head node
         String name = "ssh";
         int port = 22;
         aServ.updateVMInputEndpoint(clusterName, "Head", name, port);
         // Restarting head instance
         aServ.restartVM(clusterName, "Head");
       String roleName = "Node";
       String tmpRoleName = "";
       for(int i=0; i<noi; i++) {
                  port = 43210+(i+1);
                  tmpRoleName = roleName + i;
               // Creating node instance
                aServ.createVM(clusterName, tmpRoleName, imgName, nodeType, userName, pswd);
              // Setting end points for node instance
               aServ.updateVMInputEndpoint(clusterName, tmpRoleName, name, port);
              // Restarting node instance
             aServ.restartVM(clusterName, tmpRoleName);
      // Method to update the input endpoint details 
      public void updateVMInputEndpoint(String clusterName, String vmName, String name, int port)
        throws Exception {
                VirtualMachineGetResponse resp = computeManagementClient.getVirtualMachinesOperations().
                                                        get(clusterName, clusterName, vmName);
                VirtualMachineUpdateParameters updateParameters = new VirtualMachineUpdateParameters();
                //get the configuration list
                ArrayList<ConfigurationSet> configlist = resp.getConfigurationSets();
                //get inputendpoint list and update it
                ArrayList<InputEndpoint> endpointlist = configlist.get(0).getInputEndpoints();
                InputEndpoint inputEndpoint = new InputEndpoint();
                inputEndpoint.setEnableDirectServerReturn(false);
                inputEndpoint.setPort(port);
                inputEndpoint.setLocalPort(port);
                inputEndpoint.setName(name);
                inputEndpoint.setProtocol(InputEndpointTransportProtocol.TCP);
                endpointlist.add(inputEndpoint);
                // Open port for https on head node
                if(vmName.equals("Head")) {
                        inputEndpoint = new InputEndpoint();
                        inputEndpoint.setEnableDirectServerReturn(false);
                        inputEndpoint.setPort(2400);
                        inputEndpoint.setLocalPort(2400);
                        inputEndpoint.setName("https");
                        inputEndpoint.setProtocol(InputEndpointTransportProtocol.TCP);
                        endpointlist.add(inputEndpoint);
                updateParameters.setConfigurationSets(configlist);
                //required for update
                OSVirtualHardDisk osVirtualHardDisk = resp.getOSVirtualHardDisk();
                updateParameters.setOSVirtualHardDisk(osVirtualHardDisk);
                updateParameters.setRoleName(resp.getRoleName());
                OperationResponse updtResp = computeManagementClient.getVirtualMachinesOperations().update(clusterName, clusterName, resp.getRoleName(), updateParameters);
And every time i am creating a new cloud service along with head and node instances. Region is "South Central US".
I am setting ProvisionGuestAgent field to true at instance creation time. Thank you.
