Comment 17 for bug 1998417

Kolla Ansible deploys TLS on every endpoint by default (public and private). Every service must talk to every other service using TLS, if you self sign the cert, it will deploy your root CA and 99% of the time where things hit a snag is that strict checking is on and the service in question does not use the custom root CA to verify the cert.

Here, I believe the issue is that skyline is trying to talk to keystone to get a token, domains etc and it fails there. Logging wise, this is all i see (The log indicates a protocol error - assumed = https)

raise LocalProtocolError("illegal request line")
h11._util.RemoteProtocolError: illegal request line <---
