$teamleader->connect(); not working

[Silassiai]

followed your examples. Below error is what i get after redirect when using the authorization code and all required TeamLeader params where filled.

Error!: Error 400: Could not aquire or refresh access token: The request is missing a required parameter, includes an invalid parameter value, includes a parameter more than once, or is otherwise malformed.

So it fails in the acquireAccessToken method. On the below call:
post: https://focus.teamleader.eu/oauth2/access_token
params: (*** are sensored)

array(1) {
  ["form_params"]=>
  array(5) {
    ["client_id"]=>
    string(32) "***"
    ["client_secret"]=>
    string(32) "***"
    ["code"]=>
    string(896) "***"
    ["grant_type"]=>
    string(18) "authorization_code"
    ["redirect_uri"]=>
    string(101) "https%3A%2F%2F***%2Fdevelopment%2Fadmin%2Findex.php%3FPage%3DAddons%26Addon%3Dteamleader"
  }
}
