AWX and insecure docker registry

,

I’m trying to use a custom EE with an insecure docker registry (following 14.1.3 of page https://docs.ansible.com/automation-controller/latest/html/userguide/execution_environments.html). When trying to use it in a job template the execution of the job fails with the following error message:

http: server gave HTTP response to HTTPS client
Is it possible to tell AWX to use this registry even if it is insecure?

Thanks
