moved my site to a webiste builder this weekend. www.mydomain loads perfectly. but type the domain without www and it times out.

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 teh root domain, but my hosts zone editor refuses and says a CNAME cannot coexist with other records. i dont want to lose visitors who type the short version. whats teh correct way to handle this? id love to understand the why, not just copy another record from a forum. what am i doing wrong??
