The typical cause of this error is a mismatch in the security bindings between the SOAP Service and the Security Expert Data Service. For example if you enable the Windows Authentication checkbox in the Security Expert installer but not in the SOAP Service installer (or vice versa) then you have a mismatch.
Either uninstall the SOAP service and update the checkbox selection to match whatever was selected in the Security Expert installer, or follow the instructions under Troubleshooting | Communication Fault/Failure in the SX-WEB Web Client Installation Manual.pdf for editing the config files of the SOAP service to match the Security Expert Data Service.
