Hey Melissa -- Thank you for posting your concern here in our Community. There are a lot of factors why the SSL certificate is not showing up on your custom domain. This can be from the website provider where you have another SSL enabled or there's another IP address in the A records with the same host. I highly suggest reaching out to our 24/7 support team to look into the issue. You can reach us here: https://convertkit.com/support21
