Cannot open keepass database on IOS anymore


I am using nextcloud to store my Keepass database and access it from different clients. Until recently I could import a new version of the DB on IOS by using the ‘open with’ and selecting the KeepassTouch app. This does not work any more.

The other option is to choose ‘Add a DB’ in Keepass touch and then select the Keepass file on the nextcloud drive. This now leads to a message, saying that I have to log into nextcloud. And then process stops!

Any idea what the problem could be here? It’s really annoying not to have access to my paswords on IOS.

Many thanks for your support.
