Images not showing after moving site (and troubleshooting)

I moved (actually copied, both versions are working) a wordpress site (https://inglesen100dias.com/) to a new server and domain (https://blog.inglesen100dias.com/).

I followed the process described in wordpress support (https://codex.www.ads-software.com/Moving_WordPress#Moving_WordPress_to_a_New_Server) and also used a search and replace script (https://interconnectit.com/products/search-and-replace-for-wordpress-databases/) as recommended there to fix the path of the images, so they use the new URL of the site.

Everything seems fine except the posts images, which they don’t show (as you can see if you click in both links above). But looking at the path of the images, it seems to be fine, and even if I copy the path of one of them (just the image file path in the server) and paste it in the browser the image shows fine, which means the images are actually in the correct location, but they don’t show when looking at the website.

I’ve also removed the htaccess file in case there was something going on, but nothing changes…

Any ideas?
