Hi, all  
I try to get driver.contexts, but an unknown error occurred.

# My target platform: iOS 8 (real device)

my tools version are:

# Appium-Python-Client==0.17

# enum34==1.0.4

# selenium==2.47.3

# appium ==1.4.11

# developing OS:Mac 10.10.5

Error message is as below:  
raise exception\_class(message, screen, stacktrace)  
selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. (Original error: connect ECONNREFUSED 127.0.0.1:27753

Error message from appium is as below:

I cant find further information on official document.  
Does anyone know what happened?

Thanks a lot

Hi,  
I think the function not implemented for python client.

I’ve resolved it as below:

1. Install ios\_webkit\_debug\_proxy(you can use brew command to install it) and run it like this:  
./ios\_webkit\_debug\_proxy -c **your\_device’s\_udid** :27753 -d
2. Restart your appium service and run your script.

I can get all the contexts now(with python).

But still can NOT switch to a webview and locate elements with appium 1.5.1;  
and I just saw appim 1.5.2, which said “fix issues with getting webview contexts on real devices” with this link “[Appium 1.5.2 released](https://discuss.appium.io/t/appium-1-5-2-released/9794)”, you can have a try, and I’ll also try it later.
