Webpack Dev Server and Builder has different Hash

Question

When run Webpack Dev Server it creates hash files but doesn't create real physical files - so Get 404 Error But if run Builder with Watcher it creates real hash files and I can get it from server directly

BUT: HMR says to Get different Hash then is created by Builder

SO: I have one real Hash Bundle and can get from the http://localhost:8000/..., but my Browser want get another Hash bundle that is not exist in the resource folder

raven.js:1074 GET http://localhost:8080/004e386432676c218bd0.hot-update.json 404 (Not Found)

Strange thing: next string showed twice

2 raven.js:80 [WDS] App updated. Recompiling... -> TWICE

Config below:
