Spyder: Error with kite when using work vpn

[nsluhrs]

What steps will reproduce the problem?

I just login to my work vpn after starting the software, I am using cisco any connect as my vpn client. I can not start the software if the VPN is already running.

The error is:

 File "C:\PROGRA~1\Anaconda3\lib\site-packages\spyder\plugins\completion\kite\client.py", line 108, in get_status
    self.sig_status_response_ready[dict].emit(kite_status)
TypeError: KiteClient.sig_status_response_ready[dict].emit(): argument 1 has unexpected type 'str'

The error happens constantly as long as the software is running but doesn't seem to actually break anything.

@dalthviz, please take a look at this one.

@nsluhrs could you run Spyder from the Anaconda Prompt using the --debug-info verbose flag, find a request related with the status of the kite service and try access that URL from a browser?

As an example, when I run spyder --debug-info verbose I can see in the log something like this when opening a file:

2020-04-16 11:48:25,222 [DEBUG] [urllib3.connectionpool] -> http://127.0.0.1:46624 "GET /clientapi/status?filename=C%3A%5CUsers%5CDaniel%5CDesktop%5Cuntitled0.py HTTP/1.1" 200 121

And from that I can try to access the status URL (http://127.0.0.1:46624/clientapi/status?filename=C%3A%5CUsers%5CDaniel%5CDesktop%5Cuntitled0.py) from the browser:

I think probably the error is caused by a connection error message when trying to access the status URL from localhost while using a VPN. So instead of a JSON we are getting as a response a string indicating a connection error of some kind.

@metalogical, is @dalthviz's hunch in the right direction?

[metalogical]

Seems like the most likely scenario. The work VPN is probably misconfigured: 127.0.0.1 should typically not be routed through a VPN.

[nsluhrs]

Sorry for taking so long to respond. I've included everything that I thought might be relevant. I think @metalogical has it right, however I it would be pretty difficult for me to convince the security guys at work to change anything. Would it be possible to change the error handling so it is able to continue after an error like this? Especially since I have explicitly disabled Kite and the software works fine if it encounters the error when already running.

Hi @nsluhrs, thank you for the log. Reopening this to address other possible errors regarding signals and str handling
