I maintain a Nextcloud version 20 instance on a Debian server version 10 (Buster) and I have problems to open Microsoft Office documents with the iOS App (iOS 13.3.1; NC 22.214.171.124). The app terminates with an error
(cURL error 3) and is not usable after that. I have to terminate the application to get back to the menu. This happens reproducibly with all Office documents (docx; xlsx) but only in the iOS app, on the desktop PCs they can be opened without problems. PDF documents don’t cause any problems either.
Can anyone comment on this or know where to look for the problem?
Thx & Bye Tom
