[Solved] Unuseful Saving warning

Hello,

here is what i get when i’m editing a document with collabora. (“document can not be stored on storage. Check rights or contact the administrator of the storage server”).


Yet this warning is without effect on saving because the document is finally saved, but it comes regularly and it makes the editing experience awful. I didn’t changed anything on collabora or nextcloud before it happened.
Any idea for fixing this?
thanks,

Eric

Solved by upgrade to nextcloud 12 (and corresponding version of Collabora).
