Feed not working after use domain that used to blogger

Last month, I bought a domain for my blogger(blogspot) account and installed it. But I feel like move to Wordprees because of some issue on blogger. So I take out the domain from my blogger blog after a week.

But this week, I managed to move to WordPress by using same domain which is https://www.theotherkhairul.com.

But after doing so, I found that the feed is not working on Google Reader. And, the last feed reached is the feed that on the date I take out the domain from my blogger blog.

So how to make it work? How to fix this?
