I added a custom domain to my site and it run well on browsers but when I tested the URL with Google PageSpeed it thrown an error: “Unable to resolve https://test.v2.mascot.dk/en. Try checking the URL for validity.”.
The site name is: bejewelled-smakager-a97fb2
The test URL is: https://test.v2.mascot.dk/en
Could you please help me to find the source of this problem? We need to fix this on testing phase before go to production with 19 other domains.
