Can't get thumbnail category - Magento 2.1.6

Question

I checked quite many threads about this topic but was not able to solve the issue. When I open a category overview I don't get the thumbnails. Opening the product details I can see the main image and the smaller images in the slider below. So that shouldn't be any permission issues. Magento also generates the cache directory with 4 different image sizes.

My url to the thumbnail is:

pub/media/catalog/product/cache/f073062f50e48eb0f0998593e568d857/a/a/aaa_5_2_3.jpg

find . -name "aaa_5_2_3.jpg" pub/media/catalog/product/cache/f9c7fbe9b524c081a3ccf800cbd963eb/a/a/aaa_5_2_3.jpg pub/media/catalog/product/cache/75eed2686e01eb22cb4050b2f40ddf97/a/a/aaa_5_2_3.jpg pub/media/catalog/product/cache/0f831c1845fc143d00d6d1ebc49f446a/a/a/aaa_5_2_3.jpg pub/media/catalog/product/cache/afad95d7734d2fa6d0a8ba78597182b7/a/a/aaa_5_2_3.jpg

I guess the identifier (=f073062f50e48eb0f0998593e568d857) is wrong. Where does it come from? I tried to find the php file where the path is generated but couldn't find it.

php bin/magento setup:static-content:deploy didn't help either. That's why I think the identifier is wrong.

I migrated the data from Magento 1.7.0.2 with the migration tool and copied the directory public/media/catalog to pub/media/catalog.

Maybe somebody can help me out, I'm quite new to magento.

You should try using the image resize command to pre-generate all necessary resizes.

php bin/magento catalog:image:resize

This command gets all the images sizes that have been defined in the theme XML and pregenerates the images in their correct folders.

You can also check the command documentation for more information http://devdocs.magento.com/guides/v2.1/frontend-dev-guide/themes/theme-images.html
