Original (not resized) images works fine - http://una.rc-fun.ru/s/bx_timeline_photos/rbw6fyl8vpqgbxca4ggbjkaa4bf6psxh.jpg?t=bd7e4c69c4eefd2bfa2721dfd78f6266

It just can't resize it for some reason - http://una.rc-fun.ru/image_transcoder.php?o=bx_timeline_photos_view&h=1

Please try to check if your server can download the original image from this URL -  http://una.rc-fun.ru/s/bx_timeline_photos/rbw6fyl8vpqgbxca4ggbjkaa4bf6psxh.jpg?t=bd7e4c69c4eefd2bfa2721dfd78f6266

I would suggest to login to your site by SSH and run the following command to see if image will be successfully downloaded:

wget http://una.rc-fun.ru/s/bx_timeline_photos/rbw6fyl8vpqgbxca4ggbjkaa4bf6psxh.jpg?t=bd7e4c69c4eefd2bfa2721dfd78f6266

you can then copy downloaded image to your local computer to see if it's really works.
