docker pull/login always using http instead of https - linux

Question

I installed a docker in ubuntu live 22.04 which installed on vmwrae. And I set the docker daemon.json like this
{
"registry-mirrors" : [
"https://my-domain.com"
],
"insecure-registries": [
]
}
Which https://my-domain.com is my private registry, and It is installed on another machine.
But when I use docker pull or login my private registry, docker always use http instead of https
root#root:~# docker pull my-domain.com/example/hello-world
Error response from daemon: Get "http://my-domain.com/v2/": dial tcp [::1]:80: connect: connection refused
root#root:~# docker login my-domain.com
Username: ******
Password: ******
Error response from daemon: Get "http://my-domain.com/v2/": dial tcp [::1]:80: connect: connection refused
Why does my docker always use http instead of https? I haven't set the relevant configuration.
this is my docker info:

I know what happen with my docker.
I changed the configuration (/etc/netplan/00-installer-config.yaml) to fix the IP address of the virtual machine.
network:
ethernets:
ens33:
dhcp4: false
dhcp6: true
optional: true
addresses:
- 192.168.188.137/24
routes:
- to: default
via: 192.168.188.2
nameservers:
addresses:
- 114.114.114.114
- 8.8.8.8
search:
- localhost
- local
version: 2
renderer: NetworkManager
But my domain name is intranet, not public. When I ping the private registry domain, it not return the right IP because it try to find the domain IP from public network.
root#root:~# ping my-domain.com
PING docker-iottest.midea.com(ip6-localhost (::1)) 56 data bytes
64 bytes from ip6-localhost (::1): icmp_seq=1 ttl=64 time=0.040 ms
64 bytes from ip6-localhost (::1): icmp_seq=2 ttl=64 time=0.034 ms
I must be set vmware network gateway as DNS address to analyze.
network:
ethernets:
ens33:
......
nameservers:
addresses:
- 192.168.188.2 # add the vmware network gateway IP
- 114.114.114.114
- 8.8.8.8
......
When I reload the network or reload the system, it is work and return the correct IP.
