I purchased a custom domain from Google in Blogger for my secondary blog. My primary blog has a .com registration. The new domain url doesn’t work. When I try to apply it the prompt say “url starts with invalid scheme?”
you should enter only www.your-new-fancy-domain-name-here.com – no https, no forward slashes.You can also use a different subdomain name instead of www.
Please follow steps 2 and 3 in this help article:
