i recently upgraded from ownCloud to nextCloud. I’m able to use some ownCloud Apps with my new nextCloud (ownCloud official app, Cirrus, ownCloud News Reader, …) but the official nextCloud Apps (or eg OCReader) not working (failure: “Konnte keine Verbindung aufbauen.” -> Error establishing an connection).
All other stuff is working fine.
My nextCloud URL is https://cloud.techz.one
Thanks for help
