Cannot repro at my local (macOS 10.12.6). seems like a defect of webpack-server: https://github.com/webpack-contrib/webpack-serve/issues/56 at windows.

Don't know if it can solve your problem: try to set host to localhost and revisit.

[fjc0k]

@ulivz THX😘. localhost is available.

@fjc0k can you explain please how you solved this ? I have the same error on Win 10. Thanks!

[fjc0k]

@MartonEstok open .vuepress/config.js, set host to localhost.

@ulivz maybe this is a bug by vuepress webpack config, because the others build tools is ok to use on my computer.

[fjc0k]

@ulivz if not a bug, maybe we should doc it.

// .vuepress/config.js

{
  host: 'localhost',
}

Query - why was this closed? If the default behavior has the error being thrown, shouldn't it be corrected? Or perhaps automatic reload be disabled unless the host config value is set?

@cfjedimaster It has already been fixed at https://github.com/vuejs/vuepress/commit/4d5c50e4455fdea18fbd62225889f70654d4b0c0, I think.

[cfjedimaster]

Ah - I assume that's not live yet? (I Installed yesterday.)

[andreapernici]

Me too. I installed it yesterday and still see the error.

Is there any chance to have this fixed?
