OneTrueError and the WCF test client

When using Microsoft WCF Test Client and you can discover and access the service and create proxy or stubs, this means the service is available. It will work properly if you add the service reference like in the following:

<system.serviceModel>
        <bindings>
            <netTcpBinding>
                <binding name="NetTcpBinding_IService1" />
            </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://127.0.0.1/service/" binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_IService1" contract="ServiceReference1.IService1"
                name="NetTcpBinding_IService1">
                <identity>
                    <userPrincipalName value="……." />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>

Since the error indicates the current proxy is not valid or the client-side configuration doesn’t match the proxy, you should follow what the error says. Start a new proxy by adding the service reference. And then in service reference, just put the service address and click Go then it will automatically create a new proxy for you. See if this fixes the problem.

If the problem continues, enable the WCF tracing to find what causes it.
