Incorrect image link at Post

After I migrated my blog from wordpress.com to my home server, I find I get a problem to see the images at posts.

The images became an icon with black/white cross. And when I click the cross icon to open the link, I got:
https://i1.wp.com/192.168.31.56/wp-content/uploads/2015/11/2015-11-12_065449.jpg This link cannot get anything.

However, if I change the link to
https://jameszzyhfm.com/wp-content/uploads/2015/11/2015-11-12_065449.jpg I can open the link to see image.

It seems I need to replace all https://i1.wp.com/192.168.31.56 with https://jameszzyhfm.com.

Is there any way to do this?
