Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it

[HeyHarry3636]

Describe the bug
Receiving the error below

HTTPConnectionPool(host='localhost', port=9515): Max retries exceeded with url: /session (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000002488E324A10>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))

Version
v0.46.04

To Reproduce

1. Run my batch file which launches chrome driver and then changedetection script

start /d "c:/users/<USERNAME>/desktop/ChromeDriver" chromedriver.exe

TIMEOUT /T 6

set WEBDRIVER_URL=http://localhost:9515

TIMEOUT /T 2

start /d "c:\Program files\Google Chrome" Chrome.exe http://127.0.0.1:5000/

start "C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python312\python.exe" "changedetection.py"

2. Attempt to check any of my watches and I receive this error.

HTTPConnectionPool(host='localhost', port=9515): Max retries exceeded with url: /session (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000002488E324A10>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))

Expected behavior
Target is the 30-year fixed interest rate in this specific case from https://www.mortgagenewsdaily.com/mortgage-rates. But this error also applies to my other watches.

Screenshots

Desktop (please complete the following information):

• OS: Windows 10 (64-bit) | 22H2 (OS Build 19045.4894)
• Browser: Chrome | 128.0.6613.138
• Chrome Driver: 128.0.6613.137
• Changedetection: v0.46.04
• Python: 3.12.6

Additional context
If I recall correctly, everything was functional at Chrome/Chrome Driver version 126.x.

Running this outside of my batch script and directly from the command prompt via changedetection.py yields the same results.

I face the same urllib3 error on Ubuntu 24 on GCP, docker and v47.03

This is a plaintext monitor:

Exception: HTTPSConnectionPool(host='ipinfo.io', port=443): Max retries exceeded with url: /ip (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f11542a5c10>: Failed to establish a new connection: [Errno -2] Name or service not known'))

Is this a new install? I ran into this problem as it was the first time I tried installing it on a windows machine. The chromedriver I installed does not have a default port and will pick a random one. It shows you in the output after running chromedriver.exe. In my case it might pick 50487. Thus I had to change my variable to this.

set WEBDRIVER_URL=http://localhost:50487

Unfortunately, after a reboot or even after stopping chromedriver.exe and restarting, it may pick another port. I am looking at a way to grab the output of the chromedriver.exe command and pass that on to the set command so I can batch start this thing.

This was not a new install, but I do continue to update my chromedriver version as my browser version auto-updates.

@mitchellm3 using your comment regarding the "The chromedriver I installed does not have a default port and will pick a random one" I forced the chromedriver to use a specific port (--port=9515) when launching and was able to clear this error. Below is my updated batch script.

start /d "c:/users/<USERNAME>/desktop/ChromeDriver" chromedriver.exe --port=9515

TIMEOUT /T 6

set WEBDRIVER_URL=http://localhost:9515

TIMEOUT /T 2

start /d "c:\Program files\Google Chrome" Chrome.exe http://127.0.0.1:5000/

start "C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python312\python.exe" "changedetection.py"

This was successful when using Chrome/Chrome Driver version 131.x

Doesn't fix the issue but it's just as easy to do a simple GET request as a fetch method than using Chrome.
