Selenium Firefox Not Working When Disconnected From Remote Desktop (RDP)

I am automating a process using Selenium Firefox and Python. I am running Selenium on a Google Virtual Instance and accessing using RDP. All went fine when I ran it through RDP, but the problem is when I disconnect from RDP, Selenium doesn't work.
The part of selenium that doesn't work is :
WebDriverWait(driver, 15).until(ec.element_to_be_clickable((By. CSS_SELECTOR,'div.van-key__wrapper:nth-child(9) div:nth-child(1)'))).click()
I have tested everything all over the internet like gpedit regedit everything and also not tell to put bat file or command to stay connected to local user like chromedriver (selenium).

I'm trying to start the chrome webdriver on linux, but it hangs, then closes

I'm making a program with selenium (python). It was working, and out of nowhere, the webdriver no longer works. I'm developing on a windows environment (and it works fine), but once I upload the code to the production server (Ubuntu), I try to open the web driver and it only displays data;, the driver hangs, then closes. No code after that continues.
Example:
print("Starting web driver")
driver = webdriver.Chrome(driver_path, options=opt)
print("Opening URL") # This code doesn't run
driver.get(config.url) # This code doesn't run
Things I've tried:
Running it on Windows (it works properly)
Updating the webdriver
Running it outside of the venv
Running the driver in a new, isolated environment
Wrapping the entire code within try-except (no errors output)
Running with the argument --headless
Edit: I'm running python3.7, chrome webdriver V 75.0.3770.90
Edit2: the driver_path var is the relative path to the chromedriver file. The opt are my list of chrome options:
opt = Options()
opt.add_argument('--no-sandbox')
opt.add_argument('--disable-dev-shm-usage')
profile = {"plugins.always_open_pdf_externally": True,
"download.default_directory": download_directory,
"download.prompt_for_download": False,
"download.directory_upgrade": True}
opt.add_experimental_option("prefs", profile)
I'm also using gunicorn as my webserver, but running it with the default (flask) webserver, I still encounter the issue. I'm also executing functions I've written for selenium through a flask-based web application (its a web app for work) The ubuntu machine that's running the script has a desktop environment installed.
After 15-25 seconds, the windows closes with no output in the terminal. After ~90 seconds, I get a message in the terminal saying:
Message: session not created
from disconnected: unable to connect to renderer
(Session info: chrome=75.0.3770.90)
I've also noticed that the chrome driver takes more time to open than usual.
Edit3: I've literally deleted then entire virtual machine and reinstalled it from scratch, and I'm still running into the same issue, I've reverted to an older version and it still doesn't run, which makes no logical sense. My only thought is that there is some configuration error or that something is interfering with it.
Edit4: I was able to get the log from the webdriver by adding the argument --verbose
Heres the log:

I'm not too familiar with Linux, but from what I've seen in the past, I have a feeling its something to do with /etc/hosts (idk?)
Edit5:
I've noticed this started happening after I installed windscribe (vpn) which makes me think that windscribe is interfering with the connection somehow.

I turns out, windscribe (vpn) interferes with the connection to the chrome webdriver, I believe it has something to do with its built-in firewall, after uninstalling it, calling sudo apt autoremove -y and a reboot, it works properly!
Edit: I re-installed the VPN (windscribe) and de-activated the included firewall and it worked properly after that.

ChromeDriver Does Not Open Websites

I am experiencing a very strange behaviour when testing Chrome via selenium webdriver.
Instead of navigating to pages like one would expect the 'get' command leads only to the download of tiny files (no type or.apsx files) from the target site.
Importantly - this behavior only occurs when I pass chrome_options as an argument
to the Chrome driver.
The same testing scripts work flawless with firefox driver.
Code:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options # tried with and without
proxy = '127.0.0.1:9951' # connects to a proxy application
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=%s' % proxy)
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('whatismyip.com')
Leads to the automatic download of a file called download (no file extension, Size 2 Byte).
While calling other sites results in the download of small aspx files.
This all happens while the browser page remains blank and no interaction with
elements happen = the site is not loaded at all.
No error message, except element not found is thrown.
This is really strange.
Additional info:
I run Debian Wheezy 32 bit and use Python 2.7.
Any suggestions how to solve this issue?

I tried your code and captured the traffic on localhost using an SOCKS v5 proxy through SSH. It is definitely sending data through the proxy but no data is coming back. I have confirmed the proxy was working using Firefox.
I'm running Google Chrome on Ubuntu 14.04 LTS 64-bit. My Chrome browser gives me the following message when I try to configure a proxy in its settings menu:
When running Google Chrome under a supported desktop environment, the
system proxy settings will be used. However, either your system is not
supported or there was a problem launching your system configuration.
But you can still configure via the command line. Please see man
google-chrome-stable for more information on flags and environment
variables.
Unfortunately I don't have a man page for google-chrome-stable.
I also discovered that according to the selenium documentation Chrome is using the system wide proxy settings and according to their documentation it is unknown how to set the proxy in Chrome programmatically: http://docs.seleniumhq.org/docs/04_webdriver_advanced.jsp#using-a-proxy

Splinter/Selenium running on Flask / Uwsgi does not see headless display

So here's my setup:
Using a flask server with uwsgi, and through a controller action, calling a python script that uses splinter (which uses selenium) to automate the gui. The web server doesn't have a display, so I'm using xvfb.
Sshing into the machine and running xvfb and exporting display=:99, and then running the python script works great. But running it through a controller action does not work - I get the following error:
WebDriverException: Message: The browser appears to have exited before we could connect.
(this is the same error that is returned when xvfb isn't running)
ps aux shows that xvfb is running as the same user as the web server (I've isolated everything, and have a separate controller action that executes:
p = subprocess.Popen("Xvfb :99 &", stdout=fstdout,stderr=fstderr, shell=True))
and DISPLAY is set to :99 on both root and the web server user.
I could install vncserver and try that, but I suspect I will end up with the same problem. I've also tried to avoid calling xvfb directly and using PyVirtualDisplay instead, but same problem.
edit: it errors on this line (if using splinter):
browser = Browser()
or, if selenium:
with pyvirtualdisplay.Display(visible=True):
binary = FirefoxBinary()
driver = webdriver.Firefox(None, binary)
(it errors on the last line there)
Any ideas?

Cannot create browser process when using selenium from python on RHEL5

I'm trying to use selenium from python but I'm having a problem running it on a RHEL5.5 server. I don't seem to be able to really start firefox.
from selenium import webdriver
b = webdriver.Firefox()
On my laptop with ubuntu this works fine and it starts a brings up a firefox window. When I log in to the server with ssh I can run firefox from the command line and get it displayed on my laptop. It is clearly firefox from the server since it has the RHEL5.5 home page.
When I run the python script above on the server it (or run it in ipython) the script hangs at webdriver.Firefox()
I have also tried
from selenium import webdriver
fb = webdriver.FirefoxProfile()
fb.native_events_enabled=True
b=webdriver.Firefox(fb)
Which also hangs on the final line there.
I'm using python2.7 installed in /opt/python2.7. In installed selenium with /opt/python2.7/pip-2.7.
I can see the firefox process on the server with top and it is using a lot of CPU. I can also see from /proc/#/environ that the DISPLAY is set to localhost:10.0 which seems right.
How can I get a browser started with selenium on RHEL5.5? How can I figure out why Firefox is not starting?

It looks like the problem I'm encountering is this selenium bug:
http://code.google.com/p/selenium/issues/detail?id=2852
I used the fix described in comment #9 http://code.google.com/p/selenium/issues/detail?id=2852#c9
That worked for me.
