Errors running/starting django project

Hey guys,

I'm following a Django course online, but I'm constantly running into errors right after starting the project, and running out of solutions to fix it...

Whenever I create/start a django project in PyCharm, and run it in PyCharm right after its created to see whether there are any errors, I get the following messages:

"C:\Program Files (x86)\JetBrains\PyCharm 2016.3.2\bin\runnerw.exe" C:\Python\Python36-32\python.exe C:/Users/marks/OneDrive/PyCharm/HomeSite/manage.py runserver 8000
Performing system checks...

System check identified no issues (0 silenced).

Django version 1.10.5, using settings 'HomeSite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.

Up to this point I don't get any error, but the moment I load http://127.0.0.1:8000/, the following errors appends in the log:

[15/Jan/2017 09:53:06] "GET / HTTP/1.1" 200 1767

Exception happened during processing of request from ('127.0.0.1', 50546)

    return self._sock.recv_into(b)
ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host
----------------------------------------

What is even more confusing is when I try to run the server from a simple cmd prompt and load the page, I dont get ANY errors.

I get the feeling "C:\Program Files (x86)\JetBrains\PyCharm 2016.3.2\bin\runnerw.exe" is causing the problem, I've never seen that run before "python manage.py runserver" before and I cant find a reference to runnerw in settings anywhere.

Another thing that confuses me: Exception happened during processing of request from ('127.0.0.1', 50546)

What request is being sent from port number 50546 and why does it raise an error in PyCharm, but not in cmd?

os: Windows 10

Python: 3.6 (also on version 3.5.1)

Django: 1.10.5

Anybody got an idea?

Greets, Mark

UPDATE:

Each an every time I load a page from the server, another section appends to the log, but every time it has a different port number (50567, 50577, 50589, 50615).

By the way, I haven't mentioned it before, but I've already reinstalled python 3 times, each and every time python is installed, its installed with admin privileges.

UPDATE2:

Now im also getting errors in the CMD prompt after starting the server and loading the page...

UPDATE3:

I've uninstalled python and installed Anaconda3 to see if that made a difference.

At first I thought it did, since it kept running without (unusual) errors. But now I've rebooted, restarted PyCharm and tried to start the server that way, and once again the same error popped up...

I depleted my toolbox, so if anyone has an idea or solution, I would greatly appreciate the help.
