SmartRace Connect Server cannot be started (macOS)

On some macOS versions (especially High Sierra), the SmartRace Connect Server cannot be started on some Macs when the Mac is connected to a Wi-Fi network. No QR code or IP address appears when you press the Start Server button.

There are the following possible solutions:

First, please check whether ‘Restrict IP address tracking’ is enabled in the settings of the Wi-Fi network you are connected to. If so, disable this setting and then try to start the SmartRace Connect server again (thanks to user TobsenHH for the tip).
If that doesn’t work, the only option is to connect the Mac to the router via an Ethernet/LAN cable and use this connection instead of Wi-Fi.

SmartRace is a software for Mac, tablets and smartphones and is used for timing Carrera Digital tracks in 1:32 and 1:24 scale and via the Analogue mode also for analogue tracks (e.g. Carrera Evolution, Carrera Exclusiv, Carrera Go!!!, Ninco, Scalextric or others). SmartRace either connects to the Carrera AppConnect adapter via Bluetooth or takes the measurement in analogue mode via the camera of a smartphone connected via SmartRace Connect.
