How to fix the custom subdomain is not verified issue

Domain verification takes up to 72 hours, although it often happens within a few hours if your DNS records are correct.

You can check what DNS records you have by using this service: https://toolbox.googleapps.com/apps/dig

Using it is super easy:

1) Specify your subdomain that you created for sGTM (without https:// and extra characters).

2) Select the desired record type you want to check.

Example:

1. Missing DNS records

Make sure that all required records are added. They may have been accidentally deleted by someone else.

2. Incorrect DNS records

If entries exist, make sure their values match those specified in your container on Stape.

3. Extra DNS records

Make sure there are no extra DNS records for your sGTM subdomain, only those specified in your container on Stape.

If, for example, you have extra AAAA records - this can interfere with domain verification, so you should remove them and leave only those specified in the 'Domains' section of your Stape container.

4. DNS records are proxied

If you are not using the 'Own CDN' option on Stape, make sure that proxying is not enabled for your sGTM subdomain DNS records.

Example if you are using Cloudflare. This is not correct:

This is correct:

5. Problems with CAA records

In this case, you will have a corresponding error displayed in the Stape interface.
You can find a solution to this error here: https://help.stape.io/hc/en-us/articles/9044264890525-Certificate-Authority-Authorization-CAA-records

6. No SSL certificate (for Own CDN only)

If you go with Own CDN option, you are responsible for the issuance of SSL certificate for your custom domain. Please make sure that SSL certificate is in place, only after that we can validate your custom domain from our side.

7. The container doesn't have the GTM configuration

If the container doesn't have the GTM configuration, the added custom subdomain won't be verified.

The DNS records you need to add are displayed in the Domains (Tagging Server URLs) section of your container on Stape.

1. Click on three dots on your domain -> View details

2. On the right side you'll see the records. You will need to add all the records listed here for verification to be successful.
