Unable to add domain when verifying with DNS TXT record

When trying to verify my domain using a DNS TXT record, it will not allow me to add my domain. The error is simply "Unable to add domain." If I enter other domains I own, the TXT entry is successfully generated. The domain is not added anywhere else and is owned by me. I have tried multiple times over the course of three days. If this is a conflict, how can I identify the other entry?

Hi harvec, this is a tricky situation — the "Unable to add domain" error when only one specific domain fails (while others work) usually points to one of these causes:


1. The domain may already be associated with another Apple ID:

- Apple's system can block domain verification if the domain (or a subdomain under it) was previously attempted or verified with a different Apple Account

- This is the most common cause when the TXT record generates fine but the domain still won't add

- Solution: Contact Apple Support directly and ask them to check if the domain is already tied to another account in their system


2. DNS propagation delay:

- Even though the TXT record is generated, DNS changes can take 24-72 hours to fully propagate worldwide

- Apple's verification servers may check from specific locations that haven't received the update yet

- Try waiting the full 72 hours before retrying, even if other DNS lookup tools show the record is live


3. Check for conflicting TXT records:

- Log into your domain registrar and review all existing TXT records

- If there are old or duplicate Apple verification TXT entries from previous attempts, remove them and try generating a fresh one


4. Domain format issue:

- Make sure you're entering the domain without "www" or "https://" prefix — just the bare domain (e.g., yourdomain.com)

- Some registrars add extra formatting that can cause issues


5. Contact Apple Support:

- Since you've tried multiple times over 3 days, this is best resolved by contacting Apple Support directly at support.apple.com

- Ask them to investigate the specific domain in their Apple Account system


Hope one of these points to the solution!
