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...

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

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

yeah, you said that better than me: it might work..but relying on it to is a Bad Idea (tm) 🙂

if you only care about Linux then rely away 😛
