3DS PNID Sign in error code 022-5432

I keep getting this error when I try to link a PNID to my 3DS XL. I checked the error information section on the main site and this error I’m getting is UNDOCUMENTED!
Need a fix ASAP. I tried loads of times and reinstalled Nimbus while following the guide correctly.
