Hi,
It seems that the URL of page you want to use is not allowed to show in iframe outside of its domain:
Refused to display 'https://www.realestate.com.au/property-townhouse-qld-cannonvale-125855102' in a frame because it set 'X-Frame-Options' to 'DENY'.
If you're owner of this site, kindly check the server settings to allow this.
Regards
