Remote host forcibly terminated existing connection - python

I'm trying to send an actual email to myself from my website using send_mail. I had used localhost and the following cmd command,
python -m smtpd -n -c DebuggingServer localhost:1025
in order to test it. It intercepts with no problem, but I don't see anything in my inbox.
My email provider works with SSL, so I turned it to True and enabled 'access to the mailbox using mail clients' in my mail settings.
Here is the settings.py file:
EMAIL_HOST = '178.68.164.41' # My current ip address
EMAIL_PORT = '465' # Port of the email host
EMAIL_HOST_USER = 's...6#rambler.ru' # Here is my actual email
EMAIL_HOST_PASSWORD = '.....' # Here is my actual password from my email login
EMAIL_USE_TLS = False
EMAIL_USE_SSL = True
Here is the views.py file:
from django.shortcuts import render
from django.core.mail import send_mail
from .forms import ContactForm
def contact(request):
form = ContactForm
if request.method == 'POST':
message_name = request.POST.get('name')
message_email = request.POST.get('email')
message = request.POST.get('message')
send_mail(message_name, message, message_email, ['s****6#rambler.ru'])
return render(request, 'contact.html', {'form': form})
Here's the exception:

ConnectionRefusedError while sending email through gmail using Django

I am trying to send e-mails through my Gmail account for my Django application. I'm using below configurations in settings.py file.
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST_USER = 'username#gmail.com'
EMAIL_HOST = 'smtp.gmail.com' # tried smtp-relay.gmail.com also
EMAIL_PORT = '587'
EMAIL_USE_TLS = True
EMAIL_HOST_PASSWORD = 'Gmail password / app password'
Import statements in this regard:
from django.core.mail import send_mail, EmailMessage
from django.conf import settings
Following is in my views function:
message = EmailMessage(subject=email_subject, body=email_message, from_email=settings.EMAIL_HOST_USER, to=[email, 'username#gmail.com'])
message.send(fail_silently=False)
I have tried this also:
send_mail(email_subject, email_message , settings.EMAIL_HOST_USER, [email, 'username#gmail.com'] , fail_silently=False, )
Any help is much appreciated. Please note that I have tried:
enabling less secure apps button in Gmail
Then, I disabled less secure apps, enabled 2 factor authentication and use app passwords option of Google.
Here is the complete traceback:

Sending email in Django throws Address family not supported by protocol exception

I'm sending emails using Django version 2.2 and have tested it on the local machine and it works. But the same code throws [Errno 97] Address family not supported by protocol exception.
I also couldn't find any solution online.
I have rechecked my code and there is nothing wrong in it.
I'm using google smtp server with app_password.
Below are Details.
settings.py file
EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_HOST = "smtp.gmail.com"
EMAIL_USE_TLS = True
EMAIL_PORT = 587
EMAIL_HOST_USER = "*******#gmail.com"
EMAIL_HOST_PASSWORD = "app_password"
Email Sending Function
subject = 'Account Password reset mail'
ctx = {
"user" : self.user,
"website" : settings.WEBSITE_NAME,
"site_url" : settings.WEBSITE_URL,
}
msg = render_to_string('login/forgot_password_email.html',ctx)
from_email = settings.WEBSITE_ADMIN_EMAIL
to_email = [self.cleaned_data.get('email'),]
result = send_mail(subject, '', from_email, to_email, fail_silently=False, html_message=msg)
return result
I even try to login to server through SSH and execute through the shell but returns the same error.

Django SMTPServerDisconnected error on password reset (but works elsewhere)

I'm trying to set up self-serve password resets on a django setup. I have configured it to use the in-built password reset system, and have tested everything on my dev machine, and works fine. However, in production (i.e. actually sending emails), when I try to get a password reset email, it throws an SMTPServerDisconnected error:

I'm using G-Suite (Google) as the SMTP relay; the settings I'm using are:
EMAIL_HOST = 'smtp-relay.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
The weird thing is I can send emails fine in other places within the system, using django's django.core.mail.send_mail() function.
The problem turned out to be that I hadn't set DEFAULT_FROM_EMAIL, thus django was attempting to send from a localhost email address, which Google's SMTP servers silently rejected. In other uses for send_mail() I had specified the from address, so this didn't appear as an issue there.

Where should i check to find the mistake?
I faces the same problem, it was just an unstable internet connection because the problem disappeared as I changed my connection.
