NextCloud with OnlyOffice not opening previosly saved documents - docker

Question

OnlyOffice is not opening previously saved documents after doing docker-compose down. I needed to increase the memory of nextcloud instance (docker container) so I proceeded to stop all the containers, modify the docker-compose and set everything up again.
There are no issues with new documents so far but editing previously saved ones OnlyOffice opens a blank document besides the files sizes are intact (no errors in console), still showing KB in NextCloud.

Answer 1

Please also note that you must ALWAYS disconnect you users before stop/restart your container. See https://github.com/ONLYOFFICE/Docker-DocumentServer#document-server-usage-issues
sudo docker exec onlyoffice documentserver-prepare4shutdown.sh

Answer 2

It seems that every time the containers are mounted in a NextCloud + OnlyOffice setup it generates tokens to authorize the access to the documents thru headers.
I solved it by adding a third docker volume to preserve the documentserver files. Fortunately I had a backup of my files, I removed the containers and added them again and everything it's working now.
