error when running cypress to test local web project

[gzhhong]

Hello, I start my local web service (written in nextjs and running by node) on port 8080 (command is next start -p 8080). Then I run the cypress by

cypress run --env configFile=dev

configFile=dev will use the file cypress.dev.json, the content is

{
  "baseUrl": "http://localhost:8080",
  "env": {
    "environment": "dev"
  },
  "execTimeout": 180000,
  "defaultCommandTimeout": 300000,
  "requestTimeout": 10000,
  "pageLoadTimeout": 30000,
  "responseTimeout": 10000,
  "viewportWidth": 1200,
  "viewportHeight": 1200,
  "videoUploadOnPasses": false,
  "retries": {
    "runMode": 1,
    "openMode": 2
  }
}

Then I get the error message below:

Your configFile threw an error from: /Users/zhihong/workspace/iot-portal/iot-journey-front/cypress.config.js

The error was thrown while executing your e2e.setupNodeEvents() function:

RequestError: connect ECONNREFUSED ::1:8080

    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16)

any suggestions to fix it?

Thanks a lot for help,
