Can't signup

[drique]

After running npm run start:webdev I openned chromium and tried to signup.
Nothing happens.
Developer console shows:
xhr.js:178 POST http://localhost:8080/api/v1/auth/users/signup 504 (Gateway Timeout)
and

notifications.js:29 Uncaught (in promise) TypeError: Cannot read property 'message' of undefined
    at notifications.js:29
    at index.js:8
    at redux-logger.js:1
    at dispatch (applyMiddleware.js:35)
    at authenticate.js:79

Terminal shows:
[HPM] Error occurred while trying to proxy request /api/v1/auth/users/signup from localhost:8080 to http://localhost:5000/ (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)
