Troubleshooting

I was getting a weird error in Nextcloud when choosing fonts. Scrolling to the end would show 3 "empty" fonts and totally break the interface, even making the file not editable and displaying an error message. I noticed that this was not happening in the ds:example app, so I cleared my firefox cache and reloaded the Nextcloud page and document and all was fine.

Its not possible to connect Office to Nextcloud. My Office is installing well with your script into Proxmox LXC container. But this container tell me 502 Bad Gateway nginx. I didnt touch nginx configs for now! The Welcome page is working!

Had the same issue as @master-mcfly. After digging into problem i found out that "ds-docservice.service" had errors mentioning "DB table "task_result" does not exist". Also there was nothing running on port 8000.
To fix that:
Set the onlyoffice to be the DB owner sudo -i -u postgres psql -c "ALTER DATABASE onlyoffice OWNER TO onlyoffice;"
Import the schema psql -h localhost -U onlyoffice -d onlyoffice -f /var/www/onlyoffice/documentserver/server/schema/postgresql/createdb.sql
Restart the service systemctl restart ds-docservice.service
The ss -tuln | grep 8000 should now return the doc server listening
