Missing Images after Migration

Hi,

I migrated my wordpress site from host to host, also to different domain, according to the guide at WPExplorer, however the images do not shown. I replaced the database records via “Search Replace DB Master” so the old_domain.com was set to http://www.new_domain.com. The images are still missing though (even in admin backend). If I right-click on the picture and copy its address, then put the address into browser search bar, the image works with no problems. So e.g. http://www.new_domain.com/wp-content/uploads/XY.png is the image on the web, it does not work. But if I enter this link into browser, the image does show up.

Where could be the problem?

Thanks a lot!
