I am developing stand alone server in python3 and want to use secure websockets. I did try to crate developer certificate for initial testing but looks like modern browsers do not like it.
How do you create and renew certificate for server side secure web sockets for my domain (I need to register it)
Again I ma not using traditional web server like Apache etc. If that make a difference.
Let’s say I have mydomain.com. What are the exact switches to create and renew certificate for my purpose.
I am accusing registration and renewal always must be done from server that domain belongs to?
Does it make different if my server later one will be behind Firewall or load balancer?
Also separate question: Is it possible to create certificate for DDNS? Or it has to be full own domain?
