NerdTools automatically provisions free SSL certificates from Let's Encrypt for your redirected domains.
Requirements
For SSL provisioning to succeed:
- Domain verification must be complete.
- Your domain's A record must point to the redirect server IP.
- DNS must have propagated (the server must be reachable via your domain).
The provisioning process
- You click "Provision SSL" in your dashboard.
- Our server requests a certificate from Let's Encrypt.
- Let's Encrypt verifies domain control via HTTP challenge.
- Certificate is issued and installed automatically.
- Your redirect becomes active with HTTPS support.
Troubleshooting
If SSL provisioning fails:
- DNS not pointing correctly — Double-check your A record points to the correct IP.
- DNS not propagated — Wait longer and try again.
- Rate limits — Let's Encrypt has rate limits. If you've requested many certificates recently, wait an hour.
Certificate renewal
Certificates are renewed automatically before expiration. No action is required on your part.
