Created attachment 107258 [details] example-error-in-korganizer Instead of not very clear/noticeable 'Network error 8: 1' and 'Network error 3: 1' messages at the bottom - display 'Internet connection was lost' and 'No internet connection' in more vibrant red color. Also possibly display such fatal error messages in the middle of addon list placeholder - like Akonadi error message in KOrganizer (screenshot attached) or similar. Tested in Login Screen (SDDM) -> Get New Theme
Add timeout for 'Initializing' spinner - display error after timeout and also possibly display 'Try Again' button/link.
