Planes seen by my radar not showing up on FR24 site

Hi All,

I am using a DVB-T dongle with Raspberry Pi to feed data. Last night I observed that planes seen by my radar (T-VOBL21) were not appearing on FR24 website. For example, flight FDB555, the one selected in dump1090 image, is not see on FR24 website. As seen in the last image, the feeders service on Pi seems to be running fine. What could be the reason?
