Domain problems
A domain is not added or does not open — causes and fixes.
Domain is not added
The reason is shown in the Result column of the check window. If it says "Unavailable", click the row: it shows "No response received", "Not linked" or "Verification error".
No response received
The domain did not respond through your server. Check that dig +short your-domain returns the server's IP, that the server is Online and that ports 80 and 443 are open on it. If you changed DNS recently, wait: the update can take several hours. dnschecker.org shows whether the record is visible worldwide.
Not linked or Verification error
A server other than yours responded — usually the A record still points to the old hosting. Fix the record and delete extra A, AAAA and CNAME records.
Banned
The domain is blocked on one of the selected platforms — the row shows which one. Such a domain is not added: use another one.
Domain is attached to another account
The domain is already added in another TDS.SO account, possibly in its trash. If you bought the domain from a seller, add it with the activation code. A deleted domain is released after 10 days.
Fraud
The domain is on a list of phishing or blocked domains. You cannot add it — use another domain.
Selling key not found or already used
The activation code is wrong or has already been activated. Check that you copied the whole code and write to the seller — attach a screenshot of the error.
Domain is added but does not work
Domain disappeared from the list
On a repeat check it turned out to be unavailable or blocked and was moved to the trash. Fix the cause and restore the domain from the trash.
No HTTPS
Open the domain with https:// — the certificate is issued on the first visit. If that does not help, check that port 443 is open on the server.
Domain address without a slug returns 404
The domain has no link without a slug. Create a link in Just / mode or assign a template to the domain.
Subdomain does not open
A subdomain needs its own A record or a * wildcard, see subdomains.
