Domain nameservers change in godaddy

Question

i am using GoDaddy API to change domain nameservers and sometimes i get an errors: {"code":"FAILED_NAME_SERVER_VALIDATION","message":"Failed to update nameserversDuplicate IP address","name":"ApiError"} or {"code":"FAILED_NAME_SERVER_VALIDATION","message":"Failed to update nameserversDuplicate nameservers","name":"ApiError"} I tried to google it, but not found anything useful. What it means and how to fix this? Thank in advance.

Answer 1

I interpret that as the validation on the string is failing, are you sure there are no new lines or invalid characters in the string you are submitting?
