Getting 407 Error but my proxies 100% fine

Hello! I'm trying to get access to API but can't understand what's problem with 407 ERROR. My proxies 100% correct cause i get cookies with them. Tell me, maybe i'm missing some requests? ```PROXY_CONFIGS = [ { "name": "IPRoyal Korea Residential", "proxy": "geo.iproyal.com:51204", "auth": "MYPROXYINFO", "location": "South Korea", "provider": "iproyal", } ] def get_proxy_config(proxy_info): proxy_url = f"http://{proxy_info['auth']}@{proxy_info['proxy']}" logger.info(f"Proxy being used: {proxy_url}") return { "http": proxy_url, "https": proxy_url } USER_AGENTS = [ "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.6422.113 Safari/537.36", "Mozilla/5.0 (Macintosh; Intel Mac OS X 13_5_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.6367.78 Safari/537.36", "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.6422.61 Safari/537.36", ] BASE_HEADERS = { "accept": "application/json, text/javascript, */*; q=0.01", "accept-language": "ru-RU,ru;q=0.9,en-US;q=0.8,en;q=0.7", "origin": "http://www.encar.com", "referer": "http://www.encar.com/", "sec-fetch-dest": "empty", "sec-fetch-mode": "cors", "sec-fetch-site": "cross-site", "priority": "u=1, i", } def get_dynamic_headers(): ua = random.choice(USER_AGENTS) headers = BASE_HEADERS.copy() headers["user-agent"] = ua headers["sec-ch-ua"] = '"Google Chrome";v="125", "Chromium";v="125", "Not.A/Brand";v="24"' headers["sec-ch-ua-mobile"] = "?0" headers["sec-ch-ua-platform"] = '"Windows"' return headers last_request_time = 0 async def rate_limit(min_interval=0.5): global last_request_time now = time.time() if now - last_request_time < min_interval: await asyncio.sleep(min_interval - (now - last_request_time)) last_request_time = time.time() ``` there's more but discord limits
