chatGPT Error when using Proxy

[PinnacleCoders]

chatGPT is not working through proxy when performing SSL Inspection. Works fine without SSL Inspection.
With SSL Inspection enabled, OpenAI is sending a 403 Forbidden error (verified in browser HAR file).

Anyone aware of OpenAI restricting chatGPT functionality based on user source IP Address? Or why Proxy with SSL Inspection would not be allowed?

@justcoding121 @honfika could you please suggest. This is the response I get

Following is the exception I get in Titanium web proxy.
"A client is making HTTP request via external proxy to one of the listening ports of this proxy chat.openai.com:443"

Since the proxy lib is passing all the headers and body of https request as it is. How if the server able to identify its coming via a proxy?
