Document not uploading with 4.8.2

Hi all,

I just installed and configured new version 4.8.2 with Docker, I followed officiale procedure but when I upload a new document, I get the message: New document queued for upload and will be available shortly.
I find new files into the docket in the folder: /var/lib/mayan/shared_files/

I already created a new document ttype and checked the source, I also already restared all the docker service but it’s the same.

In Tools → Worker list i see:

But I cannot understand what is wrong.

Could someone help me please?

Thank you
Fabio
