Gradio Demo "Connection errored out" Issue

[hi0001234d]

Describe the bug
When running the Gradio demo provided by Lavague's example script, it worked and completed the quicktour of PEFT, but the URL provided by gradio demo session when launched (http://127.0.0.1:7860/) fails to function correctly, and I encounter the error "Connection errored out." I followed a suggestion from another issue to use the "URL" tab and retry, but the issue persists.

To Reproduce
Steps to reproduce the behavior:

Use the provided example script (shown below).
Run the script, which launches a Gradio demo.
Open the URL provided by the demo (e.g., http://127.0.0.1:7860/).
See the error "Connection errored out."

Here is the exact example script used:
from lavague.core import WorldModel, ActionEngine
from lavague.core.agents import WebAgent
from lavague.drivers.selenium import SeleniumDriver

selenium_driver = SeleniumDriver(headless=False)
world_model = WorldModel()
action_engine = ActionEngine(selenium_driver)
agent = WebAgent(world_model, action_engine)
agent.get("https://huggingface.co/docs")
agent.run("Go on the quicktour of PEFT")
agent.demo("Go on the quicktour of PEFT")

Expected behavior
The demo should work as expected, allowing interaction via the Gradio interface.

Screenshots

Attached is the screenshot of the error "Connection errored out."

Additional Information
Python version: 3.10
Operating System: Ubuntu (latest version)

I have already reviewed the issue list and followed a similar suggestion from another issue to click on the "URL" tab and retry, but this did not resolve the problem.
