        msg.submit(user, [msg, chatbot], [msg, chatbot], queue=True).then(
            bot, chatbot, chatbot
        )
        send.click(user, [msg, chatbot], [msg, chatbot], queue=True, concurrency_limit=3).then(

        clear.click(lambda: None, None, chatbot, queue=True)
    
    app.launch(
        show_api=False, 
        share=False, 
        server_name="0.0.0.0", 
        server_port=7777, 
        debug=True,
        ssl_verify=False,
        max_threads=20
    )

When I set nginx to port 80 without an ssl, it works and there are no errors.

After hours of debug, it turns out I was just missing proxy_buffering off; in location / 😭😭😭

@AntroSafin I downgraded to “gradio<4.0” (which the last version is 3.50.2) and I am not longer seeing this issue, even without passing enable_queue=False.

When I set : app.launch(share=False, enable_queue=False)

No bugs
