Once a host is mapped and its DNS points at the server, NextDocs requests a certificate from Let's Encrypt. This usually takes less than a minute.
Renewal
Certificates are renewed automatically before they expire. There is nothing to do.
When a certificate does not arrive
| Cause | Fix |
|---|---|
| DNS still points elsewhere | Correct the A record and wait a few minutes |
| An AAAA record points elsewhere | Remove or correct it |
| The host is not mapped to the site | Ask your platform to map it |
Until the certificate is issued, browsers show a security error for the domain.
