Hello, documentation recommends using
<http://0.0.0.0:8080>
, but after starting the server, this address doesn't work.
<http://localhost:8080>
works, tho. Why is it so ?

i believe that 0.0.0.0 means to bind to all addresses on the machine - so localhost and 127.0.0.1, etc...

it is not a valid address

you can only listen on 0.0.0.0 not connect to it

connecting to 0.0.0.0 does work on some operating systems, such as Linux
that's not standard across other OSes, but binding to 0.0.0.0 and listening is definitely a standard feature

what do you connect to when you connect to 0.0.0.0? any random interface?

yeah, 0.0.0.0 is a non-routable address, so connecting to it is kinda...janky

in practice, you get "any local address" when connecting to 0.0.0.0, same as when binding. it's definitely not something you should rely on to be portable, though
