There can be several factors that can cause recordings not to retrieve the correct CSS style of your page, like:
- Your website could be in a localhost environment, an intranet, or within a VPN network. In order to function properly, Smartlook has to be installed on an entirely public website so all the data can be retrieved through a proxy to our servers.
- The recording is too short (i.e., it ends after one second) and the connection was not established, meaning the CSS style of your page wasn’t retrieved.
- Your website has dynamic CSS. Learn more here.
- You might have a firewall blocking the Smartlook proxies. Check your web security settings and make sure you have the header access-control-allow-origin:* enabled.
