Welcome to the Community!
Please make sure your domain is active before you try to change the nameservers. It can take a little time to fully register some ccTLDs (Country-code domains). If you're in an ICANN verification status over the registrant information, you'll need to resolve that first. If none of these apply, please contact the GoDaddy support team at one of the numbers below.
