  • Change DNS– Open the control panel of your device. Go to “Network and Internet”> “Network and Sharing Center”>Choose the “wifi- network”>Properties>Internet Protocol Version 4 (TCP/IPv4)>.

Next, use the following DNS server address. Write the following DNS in the respective boxes: Preferred DNS server – 8.8.8.8 9; Alternate DNS server box- 8.8.8.4. Finally, hit “Ok”. 

  • Check the logs: Try checking the logs to fix the 403 Forbidden error. All you have to do is open the Auth0 dashboard and then choose “Monitoring”>” Logs”. Now find the particular event and look for all the errors or failed exchanges. You can try searching for “Log Event Type Codes 4”. You will get the descriptions as to why you faced a particular error. 
  • Replace the old token: The ChatGPT403 forbidden error might appear because the auth0 token has expired. Once the token expires, you need to request a new token from the authentication server by adding the appropriate credentials. Once you have generated a new token, replace the old one in the application code. 
  • Ensure the API key is appropriate: Ensure you are using a valid API key with all the requisite permissions. Also, see that the API key has not reached its limit. Do not forget to cross-check the documentation. 
  • Ensure correct checkpoint: If you are using the wrong endpoint, then the forbidden error might appear. Make sure to put the correct URL with all the correct spelling and errors and use the correct checkpoint. 
  • Ensure proper authentication: The username, passwords or any other credentials used should be properly authenticated by the server. And make sure you have all the requisite permissions to access ChatGPT.
