so annoyed rn moved my site to a website builder this weekend, www.mydomain loads perfectly... but type the domain without www and it redirects to an ad page.

This site can't be reached
Check if there is a typo in my-shop-site.example.
If spelling is correct, try running Windows Network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN
The hosts docs say to add a CNAME for the root domain, but my hosts zone editor refuses and says a CNAME cannot coexist with other records. i dont wanna lose visitors who type the short version ;) Whats teh correct way to handle this? Id love to understand teh why, not just copy anohter record from a forum.
