I’m trying to add a custom domain to my project and i can’t find the option to use a Nameserver:
The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.
You can also use v0 to narrow down the possibilities.
You need to go to your domain registrar (where you bought the domain) and change the nameserver settings there. The exact steps will be different depending on which registrar you use, but they should have some documentation or support resources to guide you.
