What to do if the connection can't be verified after setting up an A record

Learn how to fix the "Connection could not be verified" error that may appear after setting up a custom domain in Studio.Design.

Why your custom domain isn't connecting, and how to fix it

To publish a site built with Studio.Design using a custom domain, follow these steps:

  1. Register your domain in the Publish panel

  2. Configure your DNS records

  3. Verify the domain connection

  4. Issue a TLS certificate

  5. Publish your site

In step 3, "Verify the domain connection," Studio.Design checks whether your domain is pointing to our servers correctly. If the connection can't be verified for any reason, an error will appear in the Publish panel. This article explains the types of errors you might see, what causes them, and how to fix them.

Types of errors

One of the following alerts will appear in the Publish panel. In most cases, these errors are caused by your DNS record settings, so you'll need to review them.

(1) The DNS setting on your domain service is not confirmed.

(2) Your domain is connected to another server

(3) Your domain is connected to multiple servers

(4) We couldn't verify your domain's DNS settings. Please wait a moment and try again. If this keeps happening, check your nameserver settings.

(5) We couldn't retrieve your domain's DNS information from its nameservers. Please check the nameserver settings on your domain service, and that the DNS service they point to has your domain and its A record.

Keep in mind that DNS setting changes generally take 2 to 48 hours to take effect. If you've only just made changes, your domain connection may not be verifiable yet. While you're waiting for the changes to apply, there's nothing you can do from the Studio.Design side to speed things up.

You can check the status of your DNS changes using external tools like Google Admin Toolbox Dig or DNSChecker.org. For details on how to use these tools, see the article below.

What to check when you're having trouble connecting or publishing a custom domain

(1) The DNS setting on your domain service is not confirmed.

This means your A record isn't pointing to Studio.Design correctly. The A record may not have been entered, or a CNAME record may have been set up instead.

Use an external tool like Google Admin Toolbox Dig to check your record settings. For details on how to use these tools, see the article below.

Common causes

If you've set up the A record but still see an error, here are some other possible causes. For details on any of these, please reach out to your DNS provider's support team.

  • You're editing the wrong DNS server
    The DNS server you added the A record to may not be the one your domain is actually using. You can check which DNS server is in use with a tool like Whois.

  • DNSSEC isn't set up correctly
    This can happen when you transfer your DNS server. If DNSSEC was left enabled on the previous DNS server during the transfer, your DNS records may not be visible externally.

(2) Your domain is connected to another server

This means a record other than Studio.Design's has been set in your DNS settings.

In your DNS settings, delete the non-Studio.Design record shown in the Publish panel, set the correct Studio.Design A record, and then try verifying the connection again.

Common causes

If you've set up the A record but still see an error, here are some other possible causes. For details, please reach out to your DNS provider's support team.

  • The name server on Onamae.com is still set to the default
    If you're using Onamae.com to manage your domain, you have several name server options. However, if the name server is still set to the default DNS (dns1.onamae.com / dns2.onamae.com), any A records you set won't be visible externally. In this case, you'll need to switch to a different name server from the Onamae.com settings page.

(3) Your domain is connected to multiple servers

This means two or more A records are set for your domain.

In your domain provider's DNS settings, delete any records without the Studio.Design mark shown in the Publish panel. Then try verifying the connection again.

(4) We couldn't verify your domain's DNS settings. Please wait a moment and try again. If this keeps happening, check your nameserver settings.

The DNS check failed. This can happen because of a temporary network problem, so wait a little while and click [Retry].

If you keep seeing the same error, the cause may be your domain's nameserver settings. Check section (5) below as well.

If you find no problem with your settings and retrying doesn't help, contact support.

(5) We couldn't retrieve your domain's DNS information from its nameservers. Please check the nameserver settings on your domain service, and that the DNS service they point to has your domain and its A record.

Studio.Design can't retrieve your domain's information from the DNS service its nameservers point to. This won't resolve on its own, no matter how long you wait.

Common causes

This happens when you've changed your nameservers on your domain service to a different DNS service, but haven't yet registered the domain and set up its A record on that DNS service.

How to fix it

1. Check your nameserver settings in your domain service's control panel.

2. On the DNS service your nameservers point to, register your domain and set up its A record.

3. Wait for the changes to take effect, then click [Retry] again.

A temporary problem on the nameserver side can also produce this message. If you don't find anything wrong with your settings, wait a while and try again.
