how to enable ssl to another port?

Hi team,
I have a certain use case that I hope you can help me.

I would like nginx to listen on multiple ssl ports on the same machine.
I have configured a server block in the nginx.conf configuration file by mentioning this:

listen 8443 ssl;

when I want to access the application by typing https://localhost:8443, I get the ERR_TUNNEL_CONNECTION_FAILED error

in few words, how to run nginx SSL on non-standard ports?

Thanks.
