I have a Django website hosted on a VPS (OS Windows server 2019). The web server is Apache 2.4 and Python version is 3.12.8. A Digicert SSL certificate successfully installed and the website is working in production under https. However, I get this error when I try to submit a login or signup form from the website in production:
URLError at /login-page/
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1000)>
Here is the complete error traceback:

Below is what my login html page look like:
<form method="POST">
{% csrf_token %}
<fieldset>
<legend >Login</legend>
{{form|crispy}}
</fieldset>
<div class="form-group mt-5">
<button type="submit">Login</button>
</div>
</form>
Below is the form from the project’s app:
class LoginForm(forms.Form):
email = forms.EmailField()
password = forms.CharField(widget=forms.PasswordInput)
captcha = ReCaptchaField(widget=CustomReCaptchaV2Checkbox())
I have unsuccesfuly explored multiple solutions proposed by previous threads with similar error:
pip install pip-system-certs
pip install certifi
python -m pip install pip-system-certs --use-feature=truststore
REQUESTS_CA_BUNDLE in the environment variable.
Please, your help is greatly appreciated!
