    To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you’re using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.

In the DNS control panel, the domain is called “”. Therefore, things like “” or “” don’t resolve, because they’re outside “”.

You need to rename the domain to “” (and create a “www” record in it).

If DigitalOcean doesn’t support renaming domains, you should add a new one and delete the old one.

I followed this link instructions:

(Pinged the domain name and typed the IP in Digital Ocean A record and got a 404 error, which is OK! Since I haven’t add any page to nginx server)

Try resetting DNS cache and then do it once again.
