Onlyoffice cannot download Files

[GaRv3]

Hey there,

I have just set up a Nexcloud Server as well as an Onlyoffice Documents Server in my Proxmox VE.

Both servers are running as expected.
Everything is running behind a Nginx Reverse Proxy.
To keep it simple let’s say the hostnames are as follows:
https://nextcloud.xyz.de
https://onlyoffice.xyz.de

So I have a DNS rewrite roule that points every *.xyz.de connection to the Nginx which resolves https://nextcloud.xyz.de to the Nexcloud server IP with port 443 and https://onlyoffice.xyz.de to the Onlyoffice Docs server IP with port 443.

I entered the server info in the Nextcould Administration section “ONLYOFFICE”. The token and secret are identical to the ones in the local.json on the Onlyoffice server.
When I click save, the check seems to pass and the settings are saved.

But when I now open the documents app and click on a document that should be edited with Onlyoffice, the browser will switch to Onlyoffice but the file cannot be downloaded:

Nexcloud Version: 31.0.1
Onlyoffice Documents Server Version: 8.3.1-25

Any suggestions?

I don’t know if it is related, but I have a similar issue, when trying to download a recently created file.

I can see said file in the website, with a preview, but as soon as I hit download, I get a 404.
As OnlyOffice and Nextcloud are independent services, it is probable that the former uses the Download endpoint to retrieve the file to open, which may be affected by the same root cause.

I switched to the integrated version of Collabora. This works - most of the time.
