I want to run two nginx services on one host. They are nginxA  and nginxB
nginxA listening on https443 port. Only the tslv1.3 protocol is available.
The configuration file is as follows:

nginxB listening  on the https444 port.
Just provide the proxy function, redirect to the https443 port(nginxA), and
only provide the tslv1.3 protocol, the configuration file is as follows:

In fact, their relationship is
nginxB(listening on 444 tslv1.3)=> proxy => nginxA(listening on 443 tslv1.3
)

But when I visit https://127.0.0.1:444
Return to 502 Bad Gateway
Among them, nginx serving port 444 has error.log:
SSL_do_handshake() failed (SSL: error:1409442E:SSL
routines:ssl3_read_bytes:tlsv1 alert protocol version:SSL alert number 70)
while SSL handshaking to upstream, client: 127.0.0.1, server: localhost,
request: "GET / HTTP/1.1 ", upstream: "https://127.0.0.1:443/", host:
"127.0.0.1:444"


Dear friends, What is the reason for this?
My first service ssl protocol version of nginxA must be tslv1.3 only. There
is no other lower version. Can I successfully access https://127.0.0.1:444
by modifying the nginxA or nginxB configuration file?
