I am trying to connect my developer instance of London to my Ansible Tower instance. I am unable to get discovery working after configuring the URL.
Failed to execute API - Failed with status code and message: 500: Failed with status code and message: 401: {"detail":"Authentication credentials were not provided. To establish a login session, visit /api/login/."} (ad_hoc:ansible-tower-1.0-Discover; line 63)

This is a known issues PRB1307724, ansible has changed the authentication mechanism again.
When running Ansible discovery to Ansible Tower 3.3, below error is received in Cloud API Trail:
Ansible Tower Credentials are Invalid !!!!!
This error is thrown by mid server script include:
AnsibleTowerAPIBase
the actual response from ansible is:
{"detail":"Authentication credentials were not provided. To establish a login session, visit /api/login/."}
This is because even the token is provided (Token AAAAAAAAaAAAAAAAAAAAAAAAAAAAAA), however Token based authentication is no longer supported in latest Ansible Tower API 3.3.
and "Authentication credentials were not provided" is the error when credential doesn't work.
OAuth 2 is used instead in 3.3
https://docs.ansible.com/ansible-tower/3.3.0/html/administration/oauth2_token_auth.html
I tried to do this via 3rd party REST testing tool Insomnia and confirmed this.
==
However please note basic authentication is still supported.
tried to pass header: Authorization:Basic AAAAAAAAaAAAAAAAAAAA this works.

Not sure if you managed to resolve this but it's a known issues PRB1307724, ansible has changed the authentication mechanism again.

Please try replacing the "AnsibleTowerAPIBase" MidServer Script include with the one attached here.
This is just a temporary workaround until ServiceNow provides a full fix, so make sure to revert when ServiceNow patches this.
