Xlsx file is loading when i try to open it

When I try to open an xlsx file, it starts downloading. I can open the document through the context menu by selecting the “Open in OnlyOffice” option, and in this case the file is downloaded in parallel.
Everything works correctly with docx/pptx documents, it doesn’t download and opens.

I use Nextcloud 29.0.8
Onlyoffice Version: 8.3.3-18
Google chrome 135.0.7049.96

Hello, does it occur with all xlsx files? What is the version of Onlyoffice Connector’s App for Nextcloud?
Additionally, please provide the screen recording of the issue reproduction with DevTools Console and Network tabs opened.
Are you integrating Onlyoffice Docs with Nextcloud? (I am asking since you’ve added DocSpace tag which is a different product)

Good day DmitriiV
As always, I will attach the video with a link to Google Drive.
Yes, I integrate document server into my NextCloud
My version of OnlyOffice Connector is 8.2.2.22

Hello @Origimato

It does not seem to be version of the connector app, please check it out from avatar > Apps > Active Apps. By the way, what is the installation type of Document Server (Docker, DEB/RPM packages, EXE/MSI)?

Good day.
The installation was not done in Docker. I installed it in Ubuntu 24.04 LTS.
The version displayed in the application is 9.6.0

Thanks. May I know if XLSX is checked in The default application for opening the format under connector app settings?

Hello.
You are a genius. How could I not have thought of this before? You saved me!
After I checked the box and clicked save settings, xlsx files now open and do not download before opening.
Thank you very much!
