Authorize and Token Endpoint URL are not working

Hi @“Anna Wiersema” ,

Thanks for the replay, i have done the setup as per the above documentations. I have created a connected app in salesforce org also from which im generating client id and client secrete.
when i try to create new Authentication provider using client id and client secrete from salesforce connected app, i will get below screen
for Authorize end point and token end point URL, when i try to replace the domain name and try to connect to generate the token, im getting error as i mentioned above.

In documentation i didnt find any information regarding setting up Authorize and token end point URLs, can you please help me on this.
