Ensure the console has the latest system version.
If your console is already up to date, restart it by holding down the POWER Button for three seconds, then selecting "Power Options" and "Restart".
Check to see if the Joy-Con controllers have the most recent firmware update.

No more than two wireless controllers can be connected while a Bluetooth audio device is connected.
Activate and deactivate flight mode momentarily.
Once flight mode is activated, reconnect the Joy-Con controllers by enabling Bluetooth communications via "System Settings", "Flight Mode", and then "Controller Connection (Bluetooth)". Then press a button on each controller to reconnect it.Once the Joy-Con controllers are connected to the console wirelessly, deactivate airplane mode and continue to use the console as normal.
Check for wireless interference.
Ensure that the console is not placed behind a TV, under a metal object or within 1 to 1.5 metres (3 to 4 feet) of other wireless devices, such as wireless speakers, cordless phones, etc.
If possible, test the console with another Joy-Con controller (either left or right).
