Issue with setting up my pretendo account

I hadn’t yet set up a nintendo account on my 3ds, but whenever I try to link my account, it sends me this error. Is there anything I had done wrong?
error code: 022-5432

  1. Open Nimbus and switch to Nintendo
  2. Open eShop
  3. Close it and open Nimbus again
  4. Switch back to Pretendo
  5. Try signing in again now

Were you able to get this resolved?
