Recently upgraded MK4S wont connect to wifi.

Hello everyone, i have upgraded my MK4 to a MK4S today, and wanted to setup my wifi in it. It took me a while to get the prusa app working but now it runs, and using it i was able to input my network name and passphase via nfc. I then get the message on the printer about clicking finish to let it connect in the background, but it nerver does, the wifi icon in the top row of the screen always stays grey, never turns white it is supposed to when connected.
