Correct wpa_supplicant config for WPA2-Personal connection

Question

I need to setup my pi 3b+ headlessly (I dont have access to a monitor or keyboard). I have already burnt raspbian lite to my sd and added the ssh and wpa_supplicant.conf files. However, the pi does not seem to appear connected to the network at all (according to tools like Fing on my android phone).

My network has a WPA2-Personal password. My current wpa_supplicant.conf is below,

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
    ssid="RouterName"
    psk="password"
    key_mgmt=WPA-PSK
    group=CCMP TKIP
    auth_alg=OPEN
}

Any potential fixes are welcome.
