Problem after having a document open for over 30 minutes

After working in any document (Excel, Word, Powerpoint) for over 30 minutes a message like this popup:
“Unable to Refresh Lock. We will try again automatically, but you should try to save your workbook to another location or click Open in Excel.”
or
“Unable to save workbook. We will try again automatically, but you should download a copy of your workbook.”

And the only workaround is to close the document (losing any changes made after the minute 30) and reopen it.
The Office Online Server is also beeing use by OWA and this error don’t occur.

Nextcloud Details
Nextcloud version: 19.0.3
Operating system: Ubuntu Server 20.04.1
Nginx: nginx/1.19.2
PHP: 7.4.10
Office Online Server
Windows Server: 2016 latest updates installed

I don’t know if this is a misconfiguration or a bug.
Thanks in advance.
