3. Use a Different VPN Connection

Another way is to try using a different VPN if you are not able to access the ChatGPT website with your current VPN connection. There might be a scenario in which your current VPN may have been already restricted or flagged by the ChatGPT security system.

4. Disable Chrome Extension

The allowed and denied permissions can be checked with the administrator and the required permissions can be enabled or disabled and the additional permissions can be requested from the administrator.

6. Check your Router

If your IP address has been blocked by the ChatGPT security firewall, you will need to try a different IP address to use the website. Restarting your router should solve your Error 1020 since it will change your current IP.

7. Check the OpenAI Server

  • Exhausted daily limit- ChatGPT has a daily use limit and if you have already exhausted it, that might be the reason you’re seeing the 1020 error message
  • Unsafe or fraudulent activity from your IP address- If you have engaged in some unsafe activity or have an unsecured network, this may pose the ChatGPT security firewalls to block your Ip address thus displaying the 1020 error message.
  • The VPN or proxy server that you are using might be flagged- It might be possible that the proxy server or the VPN that you are using is already flagged by the ChatGPT security systems, hence the error occurs.
  • Technical issues or glitches- The technical glitches or internal errors within the ChatGPT security systems may falsely end up displaying the access denied error.
  • You may have entered the wrong login credentials- There might be a possibility that the error message is being displayed due to entering the wrong ID or Password while logging into your account.
