Check for maintenance first
Bandai Namco announces all planned maintenance on the official Digimon UP X (Twitter) account before it happens. If you're getting a connection error, that's the first place to look — maintenance windows are usually short and come with compensation (DigiEmeralds, tickets).
If it's not maintenance
- Check your own connection (Wi-Fi / mobile data) and restart the app.
- Make sure the app is updated to the latest version.
- Confirm your Bandai Namco ID (Data Link) is signed in.
