At startup (especially on first run or after device recovery), the code uses Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.Bootstrap.XconfUrl to get the xconf url.
For Comcast devices, this is set from AuthService.
If"Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.Bootstrap.XconfUrl"is unavailable or empty, the code falls back to reading the RFC xconf URL from the properties file—by default,rfc.properties.
The parameter read is "RFC_CONFIG_SERVER_URL="
Hence for testing purposes, update the rfc.properties file with the server url.
