New description:
This is my first post in stackoverflow.
I'll try to explain to you what I've done with steps and what I've done to
try to solve the problems.
# Problem
I'm struggling with the configuration of mod_wsgi for my django project.
When i try to connect to localhost:8001 (port listened by mod_wsgi) I get
an infinite loading or a "This site can’t be reached" page.
# What i've done
I have **installed apache2.4** with apachelounge
(https://www.apachelounge.com/download/) in my C:\\ drive.
I have **installed anaconda** (I haven't set conda in path) and I created
my environment for my django project (called *production*).
It runs correctly if I run the command `python manage.py runserver`
(if i go to http://localhost:7000/ (port set to manage.py) it works.
I installed mod_wsgi in my conda environment with `pip install mod-wsgi`.

tried with SetEnv in httpd.conf but it didn't work

I **added to my environment variables**

Now when i go to localhost:8001 i don't get the same error.

I tried to **set CRYPTOGRAPHY_OPENSSL_NO_LEGACY to True**
I tried writing `SetEnv CRYPTOGRAPHY_OPENSSL_NO_LEGACY 1` in httpd.conf
but it did not work, so
I added `os.environ.setdefault("CRYPTOGRAPHY_OPENSSL_NO_LEGACY", "1")` in
wsgi.py.
