# What does "CNAME Limiter introduced because of free SSL Limits" mean?

When setting up an SSL, our provider, letsencrypt blocks 5 failed attempts in a 7 day span - so we now limit that before it happens to assure you don't get blocked out of our control.

Please see [https://letsencrypt.org/docs/rate-limits/](https://letsencrypt.org/docs/rate-limits/) for more information.

| If you get limited, please do reach out and we'll confirm it's set up properly and ready to go!
