I get error ERR_NGROK_3004 when trying to connect to API.

[Zapzatron]

Windows 10
Python 3.11

package versions:

openai==1.47.0
fastapi[all]==0.115.0
ngrok==1.4.0

I used to check ngrok stop via loop, I'm trying it without the recheck loop:

async def stop_api(req_message=None):
    global is_api_stop

    if is_api_stop:
        return

    await bot.close_session()

    is_api_stop = True

    if config.USE_NGROK:
        ngrok.disconnect(webhook_tunnel_url)
        # need_check_tunnel = True
        # kill_check_time = 10  # В секундах
        # # print(dir(ngrok))
        # while need_check_tunnel:
        #     # ngrok.kill()
        #     ngrok.disconnect(webhook_tunnel_url)
        #
        #     await asyncio.sleep(1)
        #
        #     tunnel_urls = [tunnel.url() for tunnel in await ngrok.get_listeners()]
        #     # print(tunnel_urls)
        #
        #     if webhook_tunnel_url in tunnel_urls:
        #         # await errors.action_logging({}, f"Туннель не закрылся. "
        #         #                                 f"Попробую убить ngrok через {kill_check_time} секунд.")
        #         await error_manager.action_logging(None, f"Туннель не закрылся. "
        #                                                  f"Попробую ещё раз через {kill_check_time} секунд.")
        #         await asyncio.sleep(kill_check_time)
        #     else:
        #         need_check_tunnel = False

    await error_manager.action_logging(None, "API выключен :(")

    if platform.system() == "Linux" and config.IS_SYSTEMD:
        subprocess.Popen(['sudo', 'systemctl', 'stop', config.SERVICE_NAME], start_new_session=True)
    else:
        os.kill(os.getpid(), signal.SIGTERM)

I run the API as follows:

if __name__ == "__main__":
    if config.USE_NGROK:
        import ngrok

        ngrok_tunnel = ngrok.forward(f"{config.API_ADDRESS}:{config.API_PORT}",
                                     authtoken=config.NGROK_TOKEN,
                                     domain=config.DOMAIN)

        webhook_tunnel_url = ngrok_tunnel.url()

    log_level = "warning"

    if config.DEBUG_MODE:
        log_level = None

    uvicorn.run(app, host=config.API_ADDRESS, port=config.API_PORT, log_level=log_level)

I get error ERR_NGROK_3004 when trying to connect to API.
After starting ngrok, I manage to make a few requests, but the next ones result in ERR_NGROK_3004 error.
If API and ngrok are restarted, the requests come again. But this is a bad solution, because requests just do not come and it is not clear whether the API is working or not.

openai.InternalServerError: ngrok gateway error
The server returned an invalid or incomplete HTTP response.   
ERR_NGROK_3004

Also sometimes when API and ngrok are running I get an error ERR_NGROK_3200

ERR_NGROK_3200
Tunnel ....ngrok-free.app not found
