I have encountered many such problems. When it happens, the subsequent requests will be wrong. Restarting the app can't solve the problem, but restarting the network can.There's a 2 percent chance of it appearing on the terminal.

Log：

The error is called port AND at this IP address are not ready to receive. Possible explanations are:

  • the service has crashed or hasn't been started,
  • your client is trying to connect using the wrong IP address or port, or
  • server access is being blocked by a firewall that is "refusing" on the server/service's behalf. This is pretty unlikely given that normal practice (these days) is for firewalls to "blackhole" all unwanted connection attempts.
