Non-www to www not working

I’ve looked at about ten other posts and tried five things before posting this

One of my domains is set up correctly to redirect http:// to https://www. but I am for some reason unable to achieve the same result in another of my domains.
Page rules for both are / 301 https://www.x/ and /* 301 https://www.x/$1

both of the www’s resolve correctly independently?

working correctly: grify.dev
not working: blockhead.dev

Thanks :smiley:

Redirect example.com to www.example.com covers that.

In your particular case it seems you simply dont have a DNS record for your naked domain.

I do. I have a CNAME to a repl on the naked domain.

An unflattened CNAME wont work for your naked domain, furthermore your entry is not proxied.

You need to follow the tutorial.

Thanks
