Pokémon Champions Connection Error messages after the September 9 maintenance are not automatically proof that the servers are still down. The scheduled maintenance ended at around 06:00 UTC, so players who cannot log in now should first confirm that Version 1.2.0 is installed and then work through Pokémon Support’s official connection steps.
The official Pokémon Champions Connection Error troubleshooting advice for Nintendo Switch and Switch 2 focuses on connection quality, console time settings, IPv6 on Switch 2 and cache clearing. Those steps are safer than deleting save data or repeatedly reinstalling the game without knowing what is wrong.
How to Fix a Pokémon Champions Connection Error
- Make sure Pokémon Champions is updated to the current version.
- Use a strong, stable internet connection.
- Try another connection method such as Wi-Fi, LAN or a mobile hotspot.
- Make sure the console date and time are synchronized through the internet.
- On Switch 2, disable IPv6 for the network if login problems continue.
- Clear the console cache using the official system menu.
If a Pokémon Champions Connection Error appeared during the 02:00-06:00 UTC maintenance window, no local fix was expected to work because the game was intentionally unavailable. After maintenance, however, an outdated client becomes a much more likely cause.

Check the Pokémon Champions Update First
Version 1.2.0 is required for online play after the Regulation M-C update. If your Pokémon Champions Connection Error appears immediately after launching an older client, highlight Pokémon Champions on the HOME Menu, press + or -, choose Software Update, then Via the Internet.
Do not confuse Pokémon HOME updates with the Pokémon Champions game update. The software tile you need to update is Pokémon Champions itself.
Check the Console Clock
Pokémon Support specifically lists incorrect date and time settings as a possible Pokémon Champions Connection Error cause. On Switch, go to System Settings, System, Date and Time, then make sure Synchronize Clock via Internet is on.
On Switch 2, the wording is Synchronize Clock Using the Internet. Keeping the system clock synchronized avoids authentication problems caused by incorrect local time.
Try Wi-Fi, LAN or a Hotspot
A Pokémon Champions Connection Error can also come from the route between your console and the service rather than the service itself. Pokémon Support recommends trying a different connection type, including Wi-Fi, LAN or a mobile hotspot.
If one network works and another does not, that points much more strongly toward a local router or ISP route issue than a global Pokémon Champions outage.
Switch 2: Try Disabling IPv6
Pokémon Support gives one Switch 2-specific Pokémon Champions Connection Error fix: disable IPv6. Go to System Settings, Internet, Internet Settings, choose the network, select Change Settings and turn IPv6 Connection off under the IP Address section.
That step is specifically documented for Switch 2 and should not be invented as a generic fix for every platform.
Clear the Cache
Clearing cache is another official Pokémon Champions Connection Error step. On Switch, use System Settings, System, Formatting Options, Clear Cache. On Switch 2, use System Settings, System, Data-Clear Options, Clear Cache.
Clearing cache is not the same as deleting your Pokémon Champions save data. There is no reason to erase progress as a first-line connection fix.
When Is It Probably a Server Problem?
A Pokémon Champions Connection Error is more likely to be service-side if many players fail at the same time and Pokémon Champions posts a new maintenance or outage notice. The September 9 scheduled downtime is already complete, so today’s earlier maintenance should not still be blocking logins.
The official Pokémon Champions support page provides the connection and login steps used in this Pokémon Champions Connection Error guide.
