DNS Settings

Hello,

I bought a domain name from aliyun and I want to use it in a Digitalocean VM I own.

When I try and change the DNS settings to:

ns1.digitalocean.com
ns2.digitalocean.com
ns3.digitalocean.com

I get an error saying:

"Modify DNS
Domain name DNS not modified! Please change DNS to vip1.alidns.com/vip2.alidns.com!
If you do not modify DNS for resolution settings, resolution does not take effect."

Can someone please help me with this? I have no idea what I'm doing wrong

Thanks
