Consider the following scenario; A custom plugin is deployed in a Microsoft Dynamics CRM environment that executes a SOAP action to connect to an external address or service. The plugin may encounter one of the following error messages if a network proxy is required for external communication:
Unable to connect to the remote server
Unable to connect to the remote server
Error: There was no endpoint listening at <Custom Service Address> that could not accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
