Cannot telnet 2 servers through 9200 port

Hi all, i was deploy Vault and my project to 2 servers (A- Vault, B - my project), i wanna call B to A through 9200 port, but always response error : connection timeout, however when i called from local to A always had response data,
ps: my English not good, sorry about that
here is my Vault.hcl

default_lease_ttl = “24h”
disable_mlock = “true”
max_lease_ttl = “43800h”

backend “file” {
path = “/home/vault/config/data”
}

api_addr = “https://localhost:9200
ui = “true”

plugin_directory = “/home/vault/plugins”
listener “tcp” {
address = “0.0.0.0:9200”
tls_cert_file = “/home/vault/config/vault.crt”
tls_client_ca_file = “/home/vault/config/root.crt”
tls_key_file = “/home/vault/config/vault.key”
}
