Plugin stopped working

Hi there,
I’ve been using this plugin with success on a very image heavy blog migration. The job is nearly ready to go, with the exception of about 40 posts of images to be dragged over from the old site (the posts were all added after I started working on the new build, hence the sync of images required).

Anyway, long story, but it is no longer working with images from the site. Here is an example url I’m trying to pull: https://www.morrisimages.com.au/wp-content/uploads/2014/08/01-Sydney-wedding-photographer-doltone-house-loft.jpg

now I’ve tried lots of different importers over the last 12 hours and none will pull the images from the site so I’m thinking it’s something to do with the source of the files.

I checked uploads folder permissions of source site: directories 755, files 644. This seems to be normal.

Any other suggestions greatly appreciated.
