I cant contribue a solution, but I think my problem fits in here.We are using Keepass2Android on our mobile phones. We noticed some time ago, that its not longer possible to access the keepass databate which is located on a nextcloud server, which is behind a nginx on a opnsense.I just found out, that the problem was the Bot Protection of the nginx. I disabled it and now we can access the nextcloud server with Keepass2Android again. The strange thing was, that it was possible to access nextcloud with the nextcloud android app and other webdav clients all the time. Hope this info will help some people who are looking for a solution.I am also interested in a solution to enable the Bot protection again.Edit: Keepass2Android has thrown this error message: protocol=h2, code=403
