Hi Eveliina_952, I am Paulo and I'd like to help.
Are you using a laptop? Sometimes, glitches may happen so I suggest completely turning off the device and then try to connect to it again. Shut down the device properly and then once it is off, press the power button for about 5 seconds or until the led lights are completely off. Wait for a couple of minutes and then turn it on to see if the issue is fixed.
