Hello everyone,
Please help me out as I’m confused,
I have been trying to Register on the possap site for my police clearance certificate and it isn’t going through, I was told that I’m having issues with my NIN, how true can this be?

Because I’ve used this NIN for practically everything and I haven’t experienced any issue before. I’ve changed my browser and all that still saying “something went wrong” or “NIN not found”
Kindly advice please
