When you set your custom domain in Blogger. But always need to set up a subdomain in the blogger like you cannot set up example.com you have to set up www.example.com. When you try with your naked domain it always parks your website on your domain registrar websites like (Go daddy, Bigrock, Dreamhost), etc.
I have a solution to your problem. You just need to update your A records in your DNS entries.
Steps How to do:-
1. Open your Domain account and Go to Manage DNS then update A record.
Your DNS might take 48 hours to update these settings. So please have patience.
