Just because  you have created a copper area assigned to GND does not guarantee that all GND nodes will be connected together. Any pads assigned to GND can connect a local group of pads or tracks to GND via a local GND copper area but that does not mean that that local group is connected to all other local GND groups. Check the PCB Design Manager to show which nets or pads are unconnected to each other. Turn off visibility of everything except Ratlines and then look for the remaining ratlines that show local GND groups that are unconnected to each other.

ups, sorry I did not know that the one I shared was updating.... I am changing it. to find the problem. I made a clone and it is updating from the original :( there was no missing connection for sure... at that time I will try to revert. sorry,  "rookie"

@Manolocs, If you still need help on this please post the link to a public project or at least sufficient screenshots to show the extent of the issue.

Hi @manolocs - did you solve this? I have a design where the GND layer worked perfectly.  Then i changed one connector (a screw terminal with 2 pins) and i moved 6 of 12 headers.  Deleted the existing ground layer, added a new fresh one and now get the same issue you have.  For 6 headers i literally didn't move them and how it won't connect anything to the GND layer - very odd.

I found a fix for my scenario. I want to point out that the ratlines PERFECTLY showed a connection to all objects for GND. And all objects were correctly included in the GND net. Somehow the PAD itself was no longer seen as ground. by clicking each GND pad and typing GND into the box you see here and then redoing the layer fixed this. I am pretty certain this is a bug, not sure what causes it to manifest. 

@scyto Thanks I will do the same :)

You have posted no screenshots  to illustrate the issue and your project is private so only you can see it. Without - as suggested earlier - more information about your particular issue, advice on solving it is just guesswork. Simply going round editing pad netnames may solve it or it may just be a waste of your time.
