How to Fix ChatGPT “High Demand” and “Access Denied” via Proxy (2026)

ChatGPT often blocks users based on their IP or region.

1. Clear Browser Cache: Remove all openai.com cookies.
2. Use an Anti-detect Browser: Standard VPNs are often blacklisted. Using AdsPower allows you to create a clean “digital identity” that OpenAI won’t flag as a bot or restricted user.
3. Switch to 5G: Mobile IPs are less likely to be blocked than home Wi-Fi.
