Odoo18 onlyoffice connector not work

I have a onlyoffice docker installation on ubuntu 22.05. I can connect and edit documents via connectors from odoo16, nextcloud, owncloud and humhub, but not from Odoo18. When I try to configure the connector here with the same data as Odoo16 it gives me the following error:

Error while downloading the document file to be converted

Hello @vtomasi

Please check logs of Document Server for more information right after attempting to connect to Odoo 18.

By the way, what are the version and installation type of your Document Server?
