Can't see thumbnails in mobile app

[fedorow]

Hi all!

I can't find reason why android mobile don't show documents thumbnails.

I have large thumbnail generated by Share on Gallery View. I check thumbnail URL from mobile browser, it's open picture. But mobile app don't show it to me. Earlier I have made server and could see thumbnails, but i can't find the differences between these two servers.

So I found a problem. By following Alfresco Security Best Practices Guide recommendation I added protection of Alfresco API URL to my revers nginx proxy:

location ~ ^/alfresco/service/ {
 deny all;
}

But thumbnails located behind this url:

GET /alfresco/service/api/node/workspace/SpacesStore/fa575df7-4d88-4324-a814-66574cc31fb2/content/thumbnails/doclib?format=json HTTP/2.0
