Sometimes hot update is possible, sometimes not. . . I checked the information and it is related to this. How can I solve this problem~~? ?
Did you close the project port? For example, if you start npm run dev in cmd, you accidentally turn off cmd. There is no port 8080
Is your project still running? . . I think the project must have been shut down as well. If you don’t believe me, refresh with F5 and see,
The project is no longer running. . .
