Prompted to download files in IE instead of opening file in browser


When my users attempt to open a direct link to a file in I.E, they are prompted to download the file instead of view the file.

If they are already signed in to nextcloud, they do not have this issue, but if they are not logged in via the same session, they are prompted to download. If the user clicks “save” they are told the file could not be downloaded.

Does anyone have an idea why this might be happening?
