If the eShop hangs on the loading screen or crashes mid-session, start with the basics: check your Nintendo Switch's internet connection via System Settings → Internet → Test Connection. If the test passes but the shop still freezes, clear the cache by holding B while launching eShop — this forces a fresh data pull. A stuck download queue can also block the storefront, so cancel any paused downloads first.
Error codes like 2813-1450 or repeated 'incorrect password' messages usually mean a session conflict or a temporary account lock after multiple failed attempts. Wait 15–30 minutes before trying again. Make sure the email address tied to your Nintendo Account is confirmed — unverified accounts often hit walls during sign-in. If two-factor authentication is enabled, double-check that your authenticator app clock is synced correctly.
Declined transactions at checkout happen for a few reasons:
Switch to a different payment method or add Nintendo eShop funds via a prepaid card from a retail store as a workaround.
Spikes above 80–100 ms in games like Splatoon 3 or Mario Kart 8 Deluxe almost always come from a weak Wi-Fi signal. The Switch antenna is modest, so distance and walls matter more than on other devices. Move the console closer to the router or connect via a USB-to-LAN adapter for a wired connection — this alone typically cuts latency by 40–60%. Also set your router's DNS to 1.1.1.1 or 8.8.8.8 to reduce resolution delays.
If an update sits at 0% or throws error 2618-0513, the Nintendo servers may be under load. Check the official Nintendo Network Status page. If status shows green, try pausing and resuming the download, or delete the partially downloaded update data in Data Management and restart.
