Unable to get a new access token using the "Uipath Connector Guide"

Hello @Anil_G,

I have been trying with your given information but I am still unable to connect to Orchestrator. I have used the following parameters as you have given me:

I get this error Code if I try to get the Access Token:

The Error has this URL.

I believe that I have to change something about the Auth URL but after trying multiple Times im unsure what I am doing wrong. Do you know what I have to change? Is it also possible that you cannot get an access token with Postman if you only have the Community License? I have been testing out so many possibilities but none were able to get me the token.

Thank you in advance
