OpenSSL wrong version number in ruby rspec unit tests connecting to docker hashicorp vault - ruby

Question

I'm receiving the following SSL error on my rake rspec unit tests when I try to connect to the vault on my docker container using HTTPS:
OpenSSL::SSL::SSLError:
SSL_connect returned=1 errno=0 state=error: wrong version number
We're using docker to load a local instance of a hashicorp vault
Here's the command I run to generate the TLS Certificates
RUN openssl req -new -newkey rsa:4096 -x509 -sha256 -days 365 -nodes -subj "$SUBJ" -out /vault/certificates/tls/vault.crt \
-keyout /vault/certificates/tls/vault.key
When I log into the docker container and run openssl version I get:
/ # openssl version
OpenSSL 1.1.1k 25 Mar 2021
When I try to connect to the docker container from my local prompt, I get:
$ openssl s_client -connect 'localhost:8200'
CONNECTED(000001F0)

When I run this command in my local irb I get:
irb(main):001:0> require 'openssl'
=> true
irb(main):002:0> OpenSSL::SSL::SSLContext::DEFAULT_PARAMS
=> {:min_version=>769, :verify_mode=>1, :verify_hostname=>true, :options=>2147614804}
irb(main):003:0>
This is my vault configurations:
listener "tcp" {
address = "[::]:8200"
cluster_address = "[::]:8201"
tls_cert_file = "/vault/certificates/tls/vault.crt"
tls_key_file = "/vault/certificates/tls/vault.key"
}
Also, i noticed in the docker logs we have two listeners now:
Listener 1: tcp (addr: "0.0.0.0:1234", cluster address: "0.0.0.0:1235", max_request_duration: "1m30s", max_request_size: "33554432", tls: "disabled")
Listener 2: tcp (addr: "[::]:8200", cluster address: "[::]:8201", max_request_duration: "1m30s", max_request_size: "33554432", tls: "enabled")
And my docker vault server startup command is:
vault server -config=/vault/config -dev-root-token-id=myroot -dev-listen-address=0.0.0.0:1234 -dev &
And i noticed in the logs its still seeing an http connection...

I'm kind of lost right now on how to handle this.
