Python Playwright Automation Stops Unexpectedly After Closing VDS Connection

What will you learn?

In this tutorial, you will learn why a Python Playwright automation script may stop working when the VDS connection is closed and how to overcome this issue effectively.

Introduction to the Problem and Solution

When executing a Python Playwright automation script that interacts with a website or web application, a stable network connection, such as a Virtual Desktop Server (VDS), is essential. If the VDS connection is abruptly closed during script execution, it can lead to unexpected stops or failures in the automation process.

To address this challenge and ensure uninterrupted execution of Python Playwright scripts even in the event of VDS connection interruptions, implementing robust error handling mechanisms within the code becomes crucial. By incorporating exception handling techniques, we can gracefully manage network disruptions and prevent our scripts from halting prematurely.


import playwright.sync as sync

# Set up browser instance
browser = sync.chromium.launch()

# Exception handling for network interruptions
    # Your automation script here

except Exception as e:
    print(f"An error occurred: {e}")

    # Close browser instance regardless of errors

In the provided code snippet: – Import playwright.sync module for synchronous functions to simplify error handling. – Launch a Chromium browser instance using sync.chromium.launch(). – Enclose the main automation script within a try-except block to catch exceptions caused by network interruptions. – Print out any encountered error messages within the except block. – Ensure proper closure of the browser instance in the finally block even if an error occurs.

By following this structure and integrating solid error-handling practices into Python Playwright scripts, we can effectively manage issues stemming from unexpected closures of VDS connections or similar interruptions.

    How can I handle specific types of exceptions in my Playwright automation script?

    You can use distinct except blocks for various exception types to handle them individually.

    Can I resume my Playwright script after recovering from an exception?

    Yes, by incorporating recovery logic within your scripts or utilizing checkpoints to restart from where it left off.

    Is there a way to automatically reconnect my Playwright script if the network disconnects?

    Creating custom functions that periodically check connectivity status and re-establish connections when necessary is an option.

    Should I log errors encountered during automated tasks in my Playwright scripts?

    Logging errors is advisable for efficient debugging and issue tracking purposes.

    How can I simulate network interruptions for testing my Playwright scripts’ resilience?

    Tools like Wireshark or temporarily disabling internet access while running your scripts locally can be used to simulate network failures.


    In conclusion, implementing robust error-handling mechanisms in Python Playwright automation scripts is vital for ensuring stability and resilience against unforeseen events like sudden closures of VDS connections. By proactively addressing these potential challenges through effective coding practices, we enhance reliability and efficiency in automated processes.
