[JENKINS-45236] docker.withServer cannot connect using TLS

This is my pipeline script:

docker.withServer('tcp://:2376', '
            docker.withRegistry("https://.dkr.ecr.eu-west-1.amazonaws.com", "ecr:eu-west-1:6e420d6b-f42b-45f2-b7a4-7888b2f4bd14"){

                docker.image(".dkr.ecr.eu-west-1.amazonaws.com/com-pro-callbacks-collector:callbacks-collector-3").pull()

            }

        }

 

When I execute it the result is:

 docker pull .dkr.ecr.eu-west-1.amazonaws.com/com-pro-callbacks-collector:callbacks-collector-3

Post http://:2376/v1.27/images/create?fromImage=.dkr.ecr.eu-west-1.amazonaws.com%2Fcom-pro-callbacks-collector&tag=callbacks-collector-3: malformed HTTP response "\x15\x03\x01\x00\x02\x02\x16".
