Comment 1 for bug 1714412

AFAIK, "http: server gave HTTP response to HTTPS client" means the docker is missing the insecure registry option applied, like missing it in the config or having it in the config file, but puppet failed/skipped/unscheduled the docker service restart. The root cause for the latter may be the "bad" initial state of the /etc/sysconfig/docker file so augeas fails to parse it (this can be made visible with 'puppet -tvd' or the like). What is 192.168.24.1 and how it's get configured for tripleo-ci? We need to make a local reproduce and add the aforementioned debug info.

And a registry connectivity test could help to dig some details as well:

curl -s 192.168.24.1:8787/v2/_catalog | python -mjson.tool

would be nice to have it in the debug results.
