I am getting this error frequently not everytime.

HTTPConnectionPool(host=’localhost’, port=32817): Max retries exceeded
with url: /session/286f9b1508aa3fab78fee8a606577194/execute/sync
(Caused by NewConnectionError(‘<urllib3.connection.HTTPConnection
object at 0x7fd56e845400>: Failed to establish a new connection:
[Errno 111] Connection refused’))

When I send request again, it works. But doesn’t work when I send subsequent requests.

What i am doing wrong.

I am using these Chrome options.

    proxies: dict = {
        "httpProxy": proxy_string
    }
    options.proxy = Proxy(proxies)

    # Other Chrome options
    options.add_argument("--no-sandbox")
    options.add_argument("--headless")
    options.add_argument('--ignore-certificate-errors')
    options.add_argument("--disable-gpu")
    options.add_argument("--disable-software-rasterizer")
    options.add_argument("--incognito")
    options.add_argument("--disable-dev-shm-usage")
    options.add_argument("--window-size=1920,1080")
    options.add_argument("--start-maximized")
    options.add_argument("--disable-popup-blocking")
    options.add_argument("--disable-extensions")
    options.add_argument("--no-zygote")
    options.add_argument("--disable-notifications")`

Using Chrome version as 126.0.6478.55

Please let me know if any further info required.

I have tried hitting request again and again. Sometimes its working and sometimes giving exception.

I am doing one thing here

@staticmethod
    def is_instance_valid(instance):
        try:
            instance.execute_script("return true;")
            logging.info("Browser instance is valid")
            return True
        except WebDriverException:
            logging.error("Browser instance is invalid")
            return False

Can this piece of code does this?

I am downloading chrome and driver version like this in my docker file.

RUN apt-get update && apt-get install -y wget gnupg2 curl unzip 
    && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - 
    && echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list 
    && apt-get update 
    && apt-get install -y google-chrome-stable

# Check Chrome installation
RUN echo google-chrome --version
RUN google-chrome --version | awk '{print $3}' > /tmp/chrome_version.txt

RUN wget -N "https://storage.googleapis.com/chrome-for-testing-public/126.0.6478.55/linux64/chromedriver-linux64.zip" -P /tmp
