Getting GraphQL Error 503 on Localhost – “Worker exceeded resource limits” from cg.optimizely.com (Only on One Developer Machine)

Hi everyone,

I'm facing an issue when trying to fetch content via Optimizely GraphQL on my local environment. The request fails with the following error:

Error: GraphQL Error (Code: 503): 
{
  "response": {
    "error": "<!DOCTYPE html>...<title>Worker exceeded resource limits | cg.optimizely.com | Cloudflare</title>...<h2 class=\"cf-subheadline\">Worker exceeded resource limits</h2>..."
  }
}

We are using Optimizely SaaS and Only one developer machine is experiencing this issue. Other developers get this error sometime but with in 1-2 refresh attempt it auto resolve on their local machine. We are using NextJs and connecting with Optimizely SaaS CMS Dev environment.

What I've tried so far:

  • Clear the browser cache
  • Changing the ISP and IP
  • Try in different browsers
  • Re-checkout and setup again
  • Restarted the local development server

Questions:

  1. Could this be related to something specific on one machine (e.g., IP throttling, DNS, cookies, etc.)?

  2. What system-level things should I check or reset (browser cache, DNS flush, local IP, etc.) to troubleshoot or fix this?

  3. Are there any logs or headers I can inspect for more details?

Any help or guidance would be greatly appreciated!

Thanks
