LG ThinQ connection failed with “failed registration” usually means the app can’t authenticate with LG servers or the device isn’t linked to your account. Common causes are weak or unstable internet, incorrect date/time or region settings, and the need to sign out and back in or re-register the device.

Troubleshooting LG ThinQ: Failed Registration (Resolution Guide)

A quick fix for LG ThinQ failing with “failed registration” is to ensure a stable internet connection and correct date/time/region settings, then sign out of the app and sign back in and re-link the device. Also check for any app or firmware updates and retry the registration.

Important Note

Due to temporary tx/rx failures, the product registration might fail - Remove the power plug for the router and the product and wait for about one minute and then reconnect the power supplies and try again. If the registration with the mobile phone fails, then use another mobile phone for registration. (If the registration is successfully done with other mobile phone, then it is not the problem with the product.)
Check if the password is inputted correctly - After checking the password accurately, register the product again, Password inputs are case sensitive.
If the error persists, then use hot spot(tethering) for a connection. After disconnecting the router (wi-fi) connection, prepare two mobile phones and enable the hotspot (tethering) of one phone and complete product registration. If registration is made in the hotspot (tethering) environment, the issue can be seen as caused by the router.
Check the distance between the router and the product. If the product is far away from the router or they are blocked from each other with walls and so on, then the signal will be weaker and connections will fail or be unstable. Move the router to the location near the product.

[LG ThinQ] How To Troubleshoot LG ThinQ App Product Connection Issues

Follow these steps.

Step 1. On the smart phone, turn off [Mobile Data].

The product’s Wi-Fi is not connected to the internet, so go to the smartphone setting, and deactivate Mobile Data Auto Switching. Turn off the mobile data and set up an internet connection with the WI-Fi signal and then register the product.
* iPhone : Setting → Cellular → Cellular Data

Step 2. Check if the ‘Wi-Fi Auto On’ and the ‘Switch to Mobile Data’ settings are activated.

Deactivate the ‘Wi-Fi Auto On’ function and the ‘Switch to Mobile Data’ function. (Different items exist depending on the model of mobile phone from each maker, thus refer to the company guides.) The setting is used for ThinQ connections only, so after making a connection, revert it to the original setting.
Android : Setting → WiFi → Advanced → Disable Wi-Fi Auto-On iPhone (IOS) : Setting → WiFi → Disable network connection request

Step 3. Check if the Wi-Fi router supports the frequency band of 2.4GHz.

ThinQ app supports the 2.4GHz Wi-Fi band. Since ThinQ is not supported in the 5GHz environment, select the one without “5G” or “5GHz” in the network name. If it is hard to check the frequency for the wi-fi router used, then ask your internet service provider.

Step 4. Check if the router name (SSID) or password contains special characters.

Check if the router name or password contains special characters. [Ex: ★, ●, ♥ and etc] If there are special characters in it, then change the router name or password. (Except for Korean and figure type special characters, combine special characters on the keyboard ！＠＃＄％∧＆（）＿＋｜ and etc] as well as alphanumeric letters.) Delete the registered product and register it again.

Step 5. Check if ThinQ App is in the latest version.

→ If the app is not in the latest version, then update it first before registering it.
