Does the latest swift still support ssl?

[ghb-1234]

My k8s cluster version is v1.15.3, I want to use helm-v2.14.3 to install swift-v0.12.1. Without ssl, everything is ok.
But when I config ssl in swift command args 【like this https://appscode.com/products/swift/v0.12.1/guides/security/】, the swift pod is running with error message "certificate signed by unknown authority" . The full log below:
swift.log
Even I use /etc/kubernetes/ssl/ca.key&ca.crt as ca&key, or change env to k8s-v1.16.8 & helm-v2.16.1, swift pod still report the same error. What's wrong with it？
Which is the latest swift version that can support ssl, and what are the compatible k8s and helm versions?
