DRC-Incomplete Connection-GND

Really stumped on why I'm repeatedly getting a DRC error on my GND connections.  The bottom layer has a full copper layer with GND net, and everything appears properly grounded.  I'm missing something obvious, but I just can't figure it out.

Select the  net in the PCB Design Manager and look at the list of pads it connects to then check that each one is either routed or has a connection through a copper area to that net. Check that you have vias connecting single layer pads on one layer to tracks on the other layer(s).

Don't assume that because one pad is connected to another by a route or a copper area that they are connected to any other pads on the same net. Turn off the Visibility of all except the Ratlines layer and look for the ratlines showing which pads are not yet connected.

Hi It has a ratline you can change to ratline layer and shift+s, you will find out a ratline. ![图片.png](//image.easyeda.com/pullimage/h7qgM5sGi6hocFp765UqB2mwV1aIupcpFpvGWsdM.png)

Thanks--that single ratline was it.  I think what confused me, is that ALL my GND-connections were failing, even though it was just this single missed-connection.

In the **Layers and Objects panel**, select the **Ratline Laye**r and turn off the visibility of all other layers. Then repeatedly click on the Ratline Layer Visibility icon (the little eye) to toggle the visibility of the Ratlines, making them turn on and off and so make them easier to see: ![image.png](//image.easyeda.com/pullimage/rjPM2lJTCrQMMxWWU7efRf94ea4qd6EtF6twseBE.png)
