The Health check is a selftest Website provided by the running application. It shows the connections to the TF website, the TF servers, status of possible proxy servers and connected cardreaders.
Reading the results of the HealthCheck is quite easy.
In general, all tests should be true - exception: the Proxy test; only true if a proxy server is detected in the system's network settings.
The field "NbrCrDetected" represents the number of smartcard-readers that are connected.
