Vue + axios does not save session cookies

In dev mode (express on localhost:4000, vue on localhost:8080) works fine, all cookies saving correct. In production mode i change cors settings and axios.defaults.baseURL, and... client dont save cookies...

but response request contains set-cookie header

backend cors settings:

app.use(
  cors({
    credentials: true,
    origin: process.env.CLIENT_URL
  })
)

backend session settings:

app.use(
  session({
    store: new redisStore({ 
      host: 'localhost', port: 6379, client: redisClient, ttl: 86400 
    }),
    name: '_TS',
    secret: process.env.SESSION_SECRET,
    resave: false,
    cookie: { secure: false, maxAge: 600000 },
    saveUninitialized: true
  })
);

frontend:

axios.defaults.withCredentials = true
axios.defaults.baseURL = 'http://my-domain.com';

(contain session cookie!)

(session cookie is missing)

P.S. Postman works correctly, and saving cookies fine.
