Another blog is already hosted at this address.when trying to publish their blogs to a Google Custom Domain. In the past, this condition could generally (with a bit of effort, sometimes) be reset by recycling domain settings using various Google Apps wizards. Recently, though, the Google Apps solution has become less effective.
I tried doing all the trouble shooting things and it's still not working.or
I started to recycle Google Apps, and after several rounds, my www domain started to work, but the naked domain still shows me 404 error. And in "Advanced Settings", I get that naked domain error.
About half the times when Google Apps is not effective, we discover the blog previously published to a URL with mixed case letters. But the mixed case URLs don't seem to be the entire cause of the unrepairable situation. The naked domain error seems to be common in many domains that can't be repaired, too.
For the moment, it appears that the Custom Domain Reset Form will be with us, for a long time.
