Connection through copper plane improper?

Hi! I have two GND pads of a USB receptacle, that are physically well connected with GND and with each other via a copper plane, see https://i.imgur.com/jiC9uT0.png However DRC complains they are still not connected. If I connect GND pad 1 with GND pad 2 by a wire, DRC is satisfied. Why? Isn’t the connection via a copper plane proper enough? And why do they have to be interconnected?

If the two want to be connected it almost sounds like the part isn’t connected to ground in the schematic. That would explain why the two pins want to connect to each other. Odd thing is that they sure look like they are connecting to the ground plane in that picture. Assuming here that is is a ground plane with the GND net?

Is there a rats nest line or is this limited to the DRC? If you add a trace is it part of the copper GND plane or does it show a clearance around it?

Yes the green GND copper plane is well connected to GND. And in EESchema these pads of the USB receptacle are connected to GND as well. I solved it now by extending the GND pads with traces and floating vias. DRC isn’t complaining anymore. No idea what logic might be behind this, KiCAD is strange …

I suspect the thermal relief spokes are not sufficient enough to satisfy DRC. Try changing the zones connection parameters (ie. widths, clearances, etc) or try solid connections.
