Running on https://{ip}:{port}/ message contains a URL that will fail certificate verification and auth

[lordmauve]

After hypercorn starts it logs a message

[2025-12-08 17:13:04 +0000] [3686850] [INFO] Running on https://172.23.219.170:8080 (CTRL + C to quit)

This URL is not usable because the TLS certificates are only valid for the common name I provide in config.bind, not the bound IP address. Therefore clicking this URL shows a certificate error page.

Steps to reproduce

Run hypercorn with

    config = hypercorn.config.Config()
    config.bind = [f"{socket.getfqdn()}:{PORT}"]
    config.keyfile = key_path
    config.certfile = cert_path

Expected Behaviour

One or more of:

• The value of config.bind is used to construct the URL.
• Another configuration attribute is available to configure the URL that is printed.
• The message is not formatted like a hyperlink, e.g. "Listening on 172.23.219.170:8080 with TLS".
• The URL is constructed from the CN of the certificate, plus port.

Observed Behaviour

The URL is constructed by calling repr_socket_addr() on the listening socket:

hypercorn/src/hypercorn/trio/run.py

Line 72 in 0e2311f

await config.log.info(f"Running on https://{bind} (CTRL + C to quit)")

repr_socket_addr() always gives a raw network address:

hypercorn/src/hypercorn/utils.py

Line 180 in 0e2311f

def repr_socket_addr(family: int, address: tuple) -> str:
