This error means Android Studio was not able to pair your mobile device with the computer using the 6-digit code over Wi-Fi. This issue is common and usually relates to either network settings, device configuration, or how pairing is being attempted.
Solutions
Same Wi-Fi Network Required: Make sure both your computer and your phone are connected to the exact same Wi-Fi network.
Disable Randomized MAC Address: On your phone, go to Wi-Fi settings for the connected network, then find the Privacy/MAC address section and set to “Device MAC” instead of “Randomized MAC”.
Restart Wireless Debugging: On your phone, turn off Wireless Debugging in Developer Options, then turn it back on.
Restart ADB Server: In Android Studio, go to Tools > Troubleshoot Device Connections > Restart ADB Server, or in terminal run:
adb kill-server
adb start-server
Then try pairing again.
Try Command Line Pairing: Open platform-tools folder and run:
adb pair <phone_ip>:<port>
Type the pairing code when prompted. Then run:
adb connect <phone_ip>:<port>
This works better in some cases than pairing from the Android Studio UI.
Allow Network Access for Android Studio: Make sure Android Studio and adb.exe have permission for local network access in your computer’s firewall/security settings.
