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
```
# did not work
SetEnv PYTHONHOME "C:/Users/my_name/anaconda3/envs/production"
SetEnv PYTHONPATH "C:/Users/my_name/anaconda3/envs/production/Lib/site-
packages"
```
I **added to my environment variables**
- PYTHONHOME >> C:\Users\my_name\anaconda3\envs\production
- PYTHONHOME >> C:\Users\my_name\anaconda3\envs\production\Lib\site-
packages
Now when i go to localhost:8001 i don't get the same error.
# Issue 2: infinite loading

**I tried to set `WSGIApplicationGroup %{GLOBAL}` in httpd.conf**, now i
get an Internal Server Error page.
# Issue 3: internal server error (continue of Issue 2)
Now the in the ***error.log*** appears:
```
raise RuntimeError(\r
[Thu Mar 23 14:09:06.159643 2023] [wsgi:error] [pid 22156:tid 1056]

load. This is a fatal error by default, but cryptography supports running
without legacy algorithms by setting the environment variable
CRYPTOGRAPHY_OPENSSL_NO_LEGACY. If you did not expect this error, you have
likely made a mistake with your OpenSSL configuration.\r
```
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.
# Issue 4: infinite loading (again...)
When i visit localhost:8001 i get an infinite loading.
***error.log***
```

And now I'm stuck here.
