volker_muehlhaus can answer better than me but I think there is an port definition error.The ports are normally simple ports and they don't have any extension to the lower layer.
If you post your projetc file, we can answer better.

i cannot set ports on the ground .
n also not able to upload files as the sonnet software is not accessed by the uploader

Yes, the port configuration is wrong.

Remove the vias at the port. Sonnet box wall ports are grounded to the box side wall. There is no need to draw a ground via, because the box wall already creates that ground connection.

Independent of this port problem: For the via, you can draw a cover metal manually, or switch on "via pads" in the via properties.

^ Sir i did as you said but still there is 1 error as shown :

The error message is not visible in your screenshot.
Maybe you can ZIP the *.son model file and upload it here.
