Hello

I tested now and it works fine. This is how I do the test:

Install Wireguard (for simplicity I used wireguard-install)
Install the stand using the installation script
Automatically created a peer (didn't pass any arguments)

curl -X 'POST' \
  'http://SERVER_IP_ADDRESS:8081/v1/peers' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{}'

got

  {
  "publicKey": "w8z6ArpLEOXZHFF0BWHbIK9+5rX8av01+uhwtYa/CCc=",
  "presharedKey": "N1NBkN3HS9QGZpGhiYfvyxQWUsI/t2+9DZ5ubK0X3Ew=",
  "privateKey": "aJGB5OjOSwxJEEO+emIaJZognbSDjXnL4Uk7yR/CSUI=",
  "allowedSubnets": [
    "10.66.66.3/32"
  ],
  "persistentKeepalive": 0
}

Get interface config via /v1/interface

{
"privateKey": "ACvYPpYZtezCS7+teB1mVUAXyx5LbWFIquOg5G0kFFA=",
"publicKey": "tUxIJv2GXdjmPuwNuBXlJ/r3aguVNZS9y+BTmiQrJDY=",
"listenPort": 59261,
"fwMark": 0
}

And the compiled conf file:


[Interface]
PrivateKey = aJGB5OjOSwxJEEO+emIaJZognbSDjXnL4Uk7yR/CSUI=
Address = 10.66.66.3/32
DNS = 1.1.1.1

[Peer] PublicKey = tUxIJv2GXdjmPuwNuBXlJ/r3aguVNZS9y+BTmiQrJDY= PresharedKey = N1NBkN3HS9QGZpGhiYfvyxQWUsI/t2+9DZ5ubK0X3Ew= Endpoint = SERVER_IP_ADDRESS:59261 AllowedIPs = 0.0.0.0/0, ::/0



This steps give me a working connection with internet access. 
Please check your configurations and firewall. 
In #64 I'm described how to make correct conf file for wireguard client.
