Use Gatsby Netlify Template site in iframe

Hi I am using a Gatsby Netlify template and I want to embed that site inside an iframe on my other site.
At the moment it is saying, " sitename refused to connect.

How can I go about this?

@kylesloper Without more details, no one will be able to help you troubleshoot this issue.

However, I just tried including a Netlify site of mine in an iframe and it worked fine, so you might have a bad link or bad page syntax or ???
