Integration with Onlyoffice/Integracion con onlyoffice

Good evening, I have the following inconvenience install inside a vm proxmos ubuntu 20.04 for Document Server on docker with Let’s Encrypt certificates this works ok in and the docker has the following configuration

docker run -i -t -d -p 443:443 --restart=always
-v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice
-v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data
-v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice
-v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql

on the other hand, on another server, I have installed nexcloud on Ubuntu 20.04 and when I put the onlyoffice data it tells me that it is ok but when I want to save a document it tells me that “the document could not be saved, contact your administrator”
nexcloud looks good at onlyoffice with this command:

When I put this server it did not work
