yarn gen works only if server runs on port 4000

Describe the bug

Hello!

I have my api, who runs locally on port 6000... If i run "yarn gen" i get this:

 Generate outputs
  ❯ Generate src/generated/graphql.tsx
    ✖ Failed to load schema
    ◼ Load GraphQL documents
    ◼ Generate
Failed to load schema for "src/generated/graphql.tsx"
        Failed to load schema from http://localhost:6000/graphql:

        fetch failed
        TypeError: fetch failed

    at AsyncResource.runMicrotask (node:internal/process/task_queues:138:8)

        GraphQL Code Generator supports:
          - ES Modules and CommonJS exports (export as default or named export "schema")
          - Introspection JSON File
          - URL of GraphQL endpoint
          - Multiple files with type definitions (glob expression)
          - String in config file

        Try to use one of above options and run codegen again. 

If i change the server port on 4000 and change this codegen.yaml schema url to 4000, this works fine.

I TRIED TO INIALIZE THIS AGAIN with "yarn graphql-codegen init" and change the url with port 6000, but doesn't work.
Thanks!

This is very weird 🤔 there is no process in codegen that runs or uses that port. When you visit your server on port 6000 locally you it works?
