This pincode is not serviceable!

I dont know if this is a shiprocket problem or wordpress problem, I cant resolve it no matter what I try or do.

I added product dimensions, weight.
I added different shipping zones and methods.

Checked whole internet as far as I can, this issue just wouldn’t get solve.

There should be a basic check-box just to disable this “check pincode”.
