Connection refused error on NAV when connecting to web services

When you try to access Navision Web services you may encounter the following error

“This Site can’t be reached, xxxx refused to connect”

The most common reason for this error is the NAV Service is not enabled for SOAP/OData.

To enable these services, open the Microsoft Dynamics NAV Server Administration tool and select the SOAP Services Tab/ OData Services Tab  and make sure the property is set to true

Enable SOAP Services and Enable OData Services to true, if you are using SOAP you just need to enable SOAP and vice versa.

You can also use the Powershell Cmdlet

Set-NAVServerConfiugration to enable the services for example to enable OData you use the following cmdlet

Set-NAVServerConfiguration -ServerInstance <ServerInstance> -keyname ODataServicesEnabled -keyvalue true

Replace <ServerInstance> with the name of the Microsoft Dynamics NAV Server instance on which to set up OData services.

One other reason for this error is because the port is blocked and you need to create an inbound rule to allow it.
