Hello NC community, I have a very frustrating problem that is keeping me busy for days and I hope you can help me. I am self-hosting a nextcloud instance and want to use the official Android app (from F-Droid) to connect to my user account. My initial setup worked flawlessly (using app password via QR Code), but then I wiped my mobile device by accident. From then on I could not login anymore using the Android app. The app always states that the host cannot be found. I can open the very same URL in my browser, though. What I tried so far without success: - Clear Android app data - Reinstall Android app - Try Nextcloud dev app - Reinstall whole nextcloud instance incl. postgres database !!! Is there something hidden on my phone by the app that is not deleted on uninstall? Thanks Max UPDATE: It turned out to be a firewall issue (AFWall+). ---
