If TFT Mobile suddenly shows “Connection Lost” and a Retry button, the message does not identify one confirmed cause. A temporary Riot service interruption, an unstable route between your phone and the game, or an app/device issue can look similar. Use the checks below to find the cause with the least disruption. If you are in a live match, try the in-game reconnect once first; avoid deleting the app or clearing its data until you have confirmed your account sign-in.
Research note: Riot’s public support material does not define this exact “Connection Lost / Retry” message as one specific error code. The steps below combine Riot’s service and player-support resources with Apple and Google’s general app and connection guidance. Menu names can vary by device and software version.
| What you observe | Best first move | Trade-off |
|---|---|---|
| Friends or players in your region also cannot connect, or Riot lists maintenance | Check Riot’s service notices and wait for an update. | Waiting is slower than changing settings, but avoids unnecessary app resets during an outage. |
| Other apps or websites also stall on this phone | Test another Wi-Fi network or mobile data, then check the router or carrier. | Mobile data can use your plan; public Wi-Fi may require a sign-in page. |
| Only TFT fails, while other apps work | Compare Wi-Fi with mobile data, then restart and update TFT. | A second network test uses a little time and possibly data, but helps separate a local network issue from an app or service issue. |
| The problem appears only after switching apps or locking the phone | Check background data and power-saving restrictions for TFT. | Allowing background activity can use more battery or data. |
Before changing the phone, open Riot Games Service Status. Select the region and product options available on the page, then look for current incidents or scheduled maintenance that could affect League or TFT services on mobile. A status page may not list every individual TFT symptom, so a clear page is useful evidence but not proof that every connection path is working.
If Riot reports an incident, wait for its status update and try again later. Reinstalling, clearing storage, or repeatedly changing network settings cannot repair a server-side interruption. If the status page is clear and only your phone is affected, continue with the network comparison.
Close the Retry loop, then test one change at a time. If you are on Wi-Fi, turn Wi-Fi off briefly and try TFT on cellular data. If you are on cellular data, use a trusted Wi-Fi connection. Keep the test short, especially if your mobile plan has a data cap. Google recommends checking that Android has a strong internet connection, and Apple’s troubleshooting guidance similarly starts with the device’s network connection.
If you use a VPN, proxy, or custom DNS, you can briefly test without it only if you understand how to restore your normal settings. A different route may help diagnose a routing problem, but it is not a guaranteed fix and should not require weakening device security.
First, tap Retry once while the game is open and the chosen network is stable. If it returns to the same error, switch networks once and retry. Repeated taps on the same failed connection rarely provide new information.
If the app remains stuck, close TFT from the app switcher or use your phone’s force-stop control, then reopen it. If that does not help, restart the phone. This clears a temporary app or network state without removing the game’s installed files. On iPhone or iPad, Apple’s app troubleshooting steps include closing and reopening an unresponsive app and restarting the device; on Android, Google likewise recommends restarting an app or device when an app is not working normally.
Open the Apple App Store or Google Play Store, search for Teamfight Tactics, and install an available update. If there is no update button, check for a pending operating-system update when convenient. Updates can address app defects or compatibility changes, but they will not solve an active service interruption. Riot’s TFT Player Support site is the source to check for current mobile notices and game-specific help.
Then review settings that matter to your test:
Android offers a lower-risk cache check: in Settings, open TFT’s app information and clear cache if that option is available. Device menus vary. Avoid choosing Clear storage or Clear data as an early step because those options can remove local app data and sign-in state. iOS does not provide the same per-app cache button. Reinstalling should be a last resort, after you have verified your Riot account credentials and can sign back in. Google’s Android app guidance and Apple’s iPhone/iPad app guidance explain the general restart, update, and reinstall sequence.
Use the result of your tests to choose the next step:
After making one change, reopen TFT and check whether it reaches the lobby without returning to the Retry screen. If the error happened during a match, reconnect and confirm the game itself has resumed before trying another queue. A successful lobby connection on one network, followed by a failure on another, is a more useful clue than repeatedly pressing Retry. If the game still fails across two independent connections while other apps work, preserve the details above and send them to Riot rather than resetting the whole phone.
