I've installed Red5Pro server on an AWS instance and I'm now trying to setup SSL so I can broadcast a stream. I'm not sure what the domain name is for my Red5Pro server per this part of the instructions.
To obtain a CA signed certificate from Let’s Encrypt, substitute the
email@example.com with your email address and
ssl.example.com with the fully qualified domain name for your Red5 Pro server in the command below
Any suggestions on how I can find that?
