How to enable logging for CrmServiceClient in the Xrm Tooling?

Question

I'm having trouble trying to log in to CRM Online using the latest nuget Xrm Tooling package using the connection string constructor from the special powershell cmdlet.

I get a rather useless error message "Could not connect to Dynamics CRM" and try to enable tracing for troubleshooting, but could not enable it by modifying the .dll.config file as shown below ( taken from the XrmToolbox issue on GitHub ):

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.diagnostics>
    <trace autoflush="true" />
    <sources>
      <source name="Microsoft.Xrm.Tooling.Connector.CrmServiceClient"
              switchName="Microsoft.Xrm.Tooling.Connector.CrmServiceClient"
              switchType="System.Diagnostics.SourceSwitch">
        <listeners>
          <add name="console" type="System.Diagnostics.DefaultTraceListener" />
          <remove name="Default" />
          <add name ="fileListener" />
        </listeners>
      </source>

      <source name="Microsoft.Xrm.Tooling.CrmConnectControl"
              switchName="Microsoft.Xrm.Tooling.CrmConnectControl"
              switchType="System.Diagnostics.SourceSwitch">
        <listeners>
          <add name="console" type="System.Diagnostics.DefaultTraceListener" />
          <remove name="Default" />
          <add name ="fileListener" />
        </listeners>
      </source>
    </sources>
