There seems to be a system-wide overlay (e.g. a chat bubble, color- or nightfilter) active. Most device don't allow you to enable a VPN in this case. If you can't click OK in the next dialog please disable the overlay.
The app detected that it wasn't stopped properly the last time it was active. This strongly indicates that your system chose to force stop the app without any possibility for the app to restart itself. On most devices you have a few options to prevent or at least delay the system from stopping the app. You can for example disable battery optimizations for the app in the system settings or avoid clearing the app from the list of recents. If you chose to ignore this you won't see this dialog again. You can read more and receive tips for solving this with the button below (opens an external website in your browser). Click on settings to open the Android settings where you can disable battery optimizations for Nebulo.

Thank you for using Nebulo! This app is using open-source and self-hosted third-party software to make it easier to track app crashes as soon as they occur. If and only if enabled the app is going to transmit crash reports when the app encounters a crash. These reports contain additional data about the app and your device. This includes an id which is used to track crashes coming from the same user, but can't be used to track anything else. Enabling the crash reporting is optional but would make fixing bugs easier and faster. Reports are sent securely over HTTPS Click on 'See data' below to see what kind of data is transmitted and for a link to the privacy policy.
