Please deploy a DNS TXT record under the name:

_acme-challenge.nerima.click.

with the following value:

CHkG3zOQmoa7vV5-RxB5pEuju2PK4XHvceXAoUC2jbU

Before continuing, verify the TXT record has been deployed. Depending on the DNS
provider, this may take some time, from a few seconds to multiple minutes. You can
check if it has finished deploying with aid of online tools, such as the Google
Admin Toolbox: https://toolbox.googleapps.com/apps/dig/#TXT/_acme-challenge.nerima.click.
Look for one or more bolded line(s) below the line ';ANSWER'. It should show the
value(s) you've just added.

These files will be updated when the certificate renews.
