Certificate error (SSL) when opening files with Office products via WebDav

🍱 Features & apps office

Hello,

We currently have the problem that we have integrated our Nextcloud via WebDav (only via IPv6) on a Windows Server 2022 and we cannot use any Office products via it.
We can open the files with Wordpad or LibreOffice, but the following error always occurs with Office products: “Certificate error: Internal error in the application when loading the SSL libraries” .
So it seems to be a pure Office problem, has anyone ever had this or knows which settings to change?
We have already tested various things but nothing has brought any improvement.

Thank you very much.
