I actually fixed it. Not sure why yet.
But here is what worked.
The username and password could not be variables, even if they are the same it wont work.
Also i had to end the endpoint with ‘/’ for it to work, otherwise it rejected my login credentials.
Also the project had to be an ‘UrlSegment’ but it works and i am not touching that again till it breaks
