I'm having an issue creating an install package for my application.  When I install on a clean computer (no PB installed), I receive an error
 
Application Terminated
"Error: The underlying connection was closed. An unexpected error occurred on a send". 
 
The error happens on the bolded line below.

string ls_connect_url, ls_ret, ls_tmp, soaperror, rterror
long ll_ret, lLog
integer li_pos, li_ret
repoverapimanagement1 lpo_proxy_obj2
wbsrv_soapconnection2 = CREATE SoapConnection

messagebox("debug","checking repository version")

is_repo_site='abcreporting.mus-tr.com'
ls_connect_url="https://mus-tr.com/Services/APIManagement.asmx"

TRY
ll_ret = wbsrv_soapconnection2.Createinstance( lpo_proxy_obj2, 'repoverapimanagement1',ls_connect_url)
CATCH (runtimeerror er)
MessageBox("Runtime Error", er.GetMessage())
FINALLY
END TRY

CHOOSE CASE ll_ret
CASE 100
     MessageBox("Webservice Proxy Creation Error","Invalid Proxy Name")
     return -1
CASE 101
     MessageBox("WebService Proxy Creation Error","Failed to create Proxy")
     return -1
END CHOOSE

messagebox("debug","before check version")
ls_ret=lpo_proxy_obj2.getapiversioninfo ("V1.1")
messagebox("debug - check version",ls_ret)
 
 
 
lpo_proxy_ob2 is the repoverapimanagement1, a Proxy object imported from Web service using Web Service Proxy Generator.  It has the getapiversioninfo function.  I exported the object and here's the contents:
 
$PBExportHeader$repoverapimanagement1.srx
$PBExportComments$Proxy imported from Web service using Web Service Proxy Generator.
global type repoverAPIManagement1 from NonVisualObject
end type

type variables
Protected:
string pbws_ver = ".NET"
string cs_namespace = "WebService"
string cs_class = "APIManagement1"
string cs_assembly = "musrepover.dll"
string pb_prefix = "repover"
string pb_usenvo = "YES"
string pb_target = "C:\dev11\minuscript4.0"
end variables

forward prototypes
public:
function string GetAPIVerions() alias for "<method name='GetAPIVerions' ns='WebService' pbname='GetAPIVerions'><return name='returnvalue' type='System.String' isRef='False' ArrayDim='0' IsNullableType='False' /></method>"

end prototypes
 
Let me know if there is anything else I can add to help.
