Trouble configuring Eneco Toon Integration

Hi all,
I’m hving trouble getting my Eneco Toon to work from Home Assistant. Hopefully some of you can help me configure the Eneco Toon integration.
First of all I’m currently using HassOS 4.17.
I’ve followed all steps mentioned on the Toon integration page to have a correct installation.
but still I get the following error message:
The requested redirect_uri does not match any of the whitelisted redirect_uris on the Toon developer page.
this is what my callback URL looks like:
https://192.168.1**.***:8123/auth/external/callback,http://192.168.1**.***:8123/auth/external/callback.

please help my out here!
