DVA Cannot display attachment

Dear All,

I need some help on this : In Groupwise Web is not possible to view documents ( pdf / doc / xls )  : Cannot display attachment

Webaccess 24.1.0  docker image on a separate vm, Groupwise 

Images can be viewed, just no documents

DVA console reports :

 Worker 2 returned successfully Converted File

So conversion should be working. Howver it is not.
