Only Office Docker Documents Preview Errors

Hello everyone,
I have managed to install seafile 9 Community edition with docker and I am trying to implement the document preview function.
I have followed the instructions from the official manual and I seem unable to make the preview work. Initially I was getting an internal server error but after a few modifications, which are also stated on another thread, I am now getting Document conversion failed.

This is what the convert.log displays:

[2022-04-06 22:18:02,539] [WARNING] root:193 _fetch_document_or_pdf failed to fetch document of task <type: doc, id: b88ab96740ef53249b9d21fb3fa28050842266ba> (https://*****************/seafhttp/files/d32b3462-35f1-46d5-a704-1f0573268e02/seafile-tutorial.doc): <urlopen error [Errno 111] Connection refused>

Does anyone have any suggestions on what I might be missing?

Truly thankful for your assistance.
