Ziggo wifispots

I am trying to make wifi hotspots working on the autopi.
i edit /etc/wpa_supplicant/wpa_supplicant.conf where i see the connections that i made on local.autopi.io
I add

network={
ssid=“Ziggo”
identity=“my username”
password=“my password”
pairwise=CCMP
group=CCMP
scan_ssid=0
key_mgmt=WPA-EAP
eap=PEAP
ca_cert="/etc/certs/Ziggo.der" <-- the Ziggo certificate we have to use
phase1=“peapver=0”
phase2=“auth=MSCHAPV2”
}

This seems to work fine until i log in on local.autopi.io to add another network.
After that the Ziggo network disappears.

I must be editing the wrong file to do this since minion changes this file with networks from a differend location.

So my question is ? Where is minion storing the network data so my Ziggo connection stays in the list?
