The Nextcloud language settings should be used in Onlyoffice, but I didn’t test…
Perfect!! That worked. Good you found that, during my search I only found difficult settings in config files and templates

Hi @Bulat ,
did you enter the right jwt secret in the Nextcloud onlyoffice app setting?
Which distro are you using?
Updated Onlyoffice to 8.1.1.2.
The Nextcloud OnlyOffice app settings need to be saved (via “Save” button) once to make it work.

Thanks for testing!
I can confirm.
One note tho, please allow a minute after updating before going to the Nextcloud OnlyOffice app and press save. If you are too fast it will result in an error, trying to save again after a minute will result in success.

Thanks for testing and yes, Onlyoffice needs some time until it’s up and running again.
Good things take time.

I use: NS8 image ns8-rocky-linux-9-ns8-stable.qcow2
I got the key from the instructions: runagent -m onlyoffice1 grep JWT_SECRET environment
After updating Onlyoffice to version 8.1.1.26
The error remains “Error when trying to connect (Error occurred in the document service: Error while downloading the document file to be converted.) (version 8.1.1.26)”
By trial and error I think I figured out the cause of the problem. 
When I first launched NS8 image
I issued Hostname Node - next.domain.com
Now I changed Hostname Node to - box.domain.com
The rest remained the same:
Nextcloud application Hostname - next.domain.com
Onlyoffice application Hostname - office.domain.com
And now everything works 
This needs to be taken into account or warnings added to the documentation.

I added a sentence about using an unique FQDN to the NS8 Onlyoffice docs on Github.
