Changed domain, but site preview goes to old domain

I’ve successfully changed my site domain. The site displays as expected in a browser.

However, when I go to Parked at Loopia, the site preview panel to the right shows an error of “ refused to connect”

Both the config url and config admin.url options for Ghost are set to

How can I fix the preview? Thanks.

Have you restarted ghost, and refreshed the admin page?
