Python Console not connecting

Hello, 

The error looks like AV, FW  restriction. Do you have any? Please try disabling it. 

Ah yes that's probably it. Unfortunately this PC is managed by our IT department and I'm not sure if they will be willing to let it through. I asked before, but as it is impacting my work, hopefully they will!

I have admin right (and try to use it) and in cmd also connection work fine, and  error only inside PyCharm

requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', por
t=8707): Max retries exceeded with url: /hvr/api/users (Caused by NewConnectionEr
ror('<urllib3.connection.HTTPConnection object at 0x000001EA72654AC8>: Failed to
establish a new connection: [WinError 10061] No connection could be made because
the target machine actively refused it'))

also I try to disable firewall - this not helps.

@... Firewalls can block network traffic for specific processes. So if PyCharm process is blocked, so is any python process it spawns. Please try disabling any firewall software you may have.

I disable firewall - this not helps.
also i try run simple testing file

from requests import get
baseurl = "https://openlibrary.org/api/books"
r = get(baseurl)
print(r.status_code)
print(r.text)

and this works correct, but when i try to run this with submodule i get error

Well, the issue is specifically when you connect to localhost on port 8707. Try this:

Open terminal in PyCharm and do:

telnet localhost 8707

If you don't have telnet, you can use:

nc -vz localhost 8707

Then do the same test from system terminal (outside of IDE). Share the results.

telnet

telnet localhost 8707 Connecting To localhost...Could not open connection to the host, on port 8707: Connect failed

Test-NetConnection localhost -Port 8707

so, what I'll do next?

It means this is a network issue external to PyCharm. If you're in corporate network, please ask your system administrator to take a look. Otherwise the issue should be solved on a system level.

yes, it was not a PyCharm problem, its because I recently add server link for shell script for run venv, but don't append environment variable for PyCharm, so its was the reason why PyCharm try to find sever as localhost
