Hi, I have a problem that might be of similar kind. I’m on Nextcloud/Hetzner’s Storage Share 17.0.0, Phonetrack Nextcloud 0.5.10 and Phonetrack-Android v0.0.13 (two devices; F-droid). Devices use their own users accounts of NC/Storage Share. Signed in to the accounts in Phonetrack-Android via SSO (making use of the Nextcloud app’s account in the phone).
A couple of months ago Hetzner decided to relabel their hosted Nextcloud as Storage Share (for licensing reasons). After that Phonetrack-Android started to give an error message nn one of the devices : “Uploading failed: Server response error”. Cannot see the device on a map. The other device I can see on a map, but cannot view tracks from it, either.
Asked Hetzner support about this. They could not help other than saying all the apps should function as before the change.
I just love this app and need it in my everyday life. Would be most greatful for hints showing a way round the problem.
