After we’ve investigated this particular issue thoroughly, it turns out that there are a couple of common scenarios that will produce this game-breaking error with PUBG. Here’s a shortlist of potential causes that will cause the Your client will now close due to the detection of an unauthorized device error: Now that we went over every potential fix that might be causing this problem, let’s go over the actual fixes that other PUBG players have successfully used to avoid the ‘Your client will now close due to the detection of an unauthorized device’ error message:
Disconnect the macro device
The first thing you should do in case you’re seeing this error is to disconnect any type of macro device (mouse of the keyboard) that you’re currently using. Keep in mind that PUBG is quite aggressive at keeping the playing level fair – don’t expect to be able to use a macro device without exposing your account to a permanent ban. Note: Any type of macro mouse or any other unauthorized service that will modify the game and give you an advantage is strictly prohibited. If you’re using such a device, disconnect it from your PC, then trigger a restart and wait for the next startup to complete before launching PUBG again. Once you have successfully removed the macro device and restarted your PC, you should be able to launch the game without getting the same “Your client will now close due to the detection of an unauthorized device” error. In case you have already removed the macro device and restarted but you’re still experiencing the error (or you didn’t use a macro device at all), move down to the next method below.
Open a support ticket
If you already removed the macro device and the game refuses to let you get past the “Your client will now close due to the detection of an unauthorized device” error even after restarting or you didn’t use a macro device at all, you should get in contact with the official PUBG support team. As it turns out, PUBG is very aggressive with prohibiting macro devices and this behavior might also be blocking devices that should normally be allowed to be used when playing the game. If this scenario is applicable to you as you’ve never used a macro device (or you’ve since disconnected it), follow the instructions below to get in contact with a PUBG support agent and share the maker and model of the keyboard and mouse that you’re using so that they can whitelist them with your game. Note: This type of problem is mainly encountered with brand new keyboard and mouse models (not macro) that PUBG’s team has not managed to whitelist yet. Follow the instructions below to open a support ticket with PUBG’s support team:
Run game in clean boot mode (NOT RECOMMENDED)
As it turns out, the PUBG service that is tasked with detecting if there’s a prohibited device currently connected to this PC will not run if you configure your PC to boot in clean boot mode. Some PUBG players have discovered this and are using this as a way to play the game using prohibited macro devices (mouse and keyboards). Important: We only featured this guide to provide you with the means to continue playing the game in case you’re experiencing the ‘Your client will now close due to the detection of an unauthorized device’ error after you’ve disconnected the macro device. Keep in mind that exploiting this loophole might get your account banned. If you run the game after booting in the clean boot mode, you should be able to get past the error message. Follow the instructions below for a step-by-step guide on performing a clean boot procedure to avoid the ‘Your client will now close due to the detection of an unauthorized device’ error: Note: There’s a lot of talks that the PUBG devs are preparing to stop this loophole from being used to get around macro restrictions. Follow the instructions below at your own risk.
