django send_mail has insecure link to http://dpaste.com/ - django

I am trying to send emails with django and for that I use send_email from django.core.mail, but it has a link to http://dpaste.com/, with HTTP and my website is in HTTPS.
This is the message I get in my console:
Mixed Content: The page at 'https://b...' was loaded over a secure connection, but contains a form that targets an insecure endpoint 'http://dpaste.com/'. This endpoint should be made available over a secure connection.
It means that the standard send_mail from django blocks my secure connection? How can that be possible? What othe solutions do I have to send email with django?
Thanks

The problem was happening because I had DEBUG: TRUE and there was an error in the code. Therefor, django was using dpaste to throw the error.
The solution was to turn the DEBUG off or fix the error in the code.
Thanks, Suresh, for helping me on that.

How to solve ERR_TOO_MANY_REDIRECT when deploying django rest framework web app to Azure?

I deployed an web app which django restframework base on Heroku and Azure.
Same app on Heroku works fine.
But when I access to Azure, it causes ERR_TOO_MANY_REDIRECT error.
I googled and found that turn SECURE_SSL_REDIRECT off solved ERR_TOO_MANY_REDIRECT error.
However, it causes 403 CSRF error instead.
I need to find another way to fix ERR_TOO_MANY_REDIRECT or find a way to fix 403 CSRF error.
Can anyone help me to solve this issue?
If your app is on "Azure App Service", the HTTPS connection will be terminated before it reaches your web worker. Your app wil see an incoming HTTP request instead. In this case you need to set SECURE_SSL_REDIRECT = False indeed. If you want to enforce HTTPS (which is a good practice) you can do so in the Azure settings: https://learn.microsoft.com/en-us/azure/app-service/configure-ssl-bindings#enforce-https
About the CSRF-related error: because Azure translates HTTPS to HTTP, you need to configure Django to allow POST requests from a different scheme (since Django 4.0) by adding this to settings.py:
CSRF_TRUSTED_ORIGINS = ["https://YOUR-DOMAIN.com", "https://www.YOUR-DOMAIN.com"]
If this does not solve your problem, you can temporarily set DEBUG = True in production and try again. On the error page, you will see a "Reason given for failure" that you can post here.

The page at https://lyrics-chords.herokuapp.com/ was not allowed to display insecure content from http://localhost:8000/auth/user

I've just finished creating a Django-React app and have pushed the changes to Heroku. The frontend (JS and CSS) appear on the website no problem, but requests to the backend result in the following error:
[blocked] The page at https://lyrics-chords.herokuapp.com/ was not allowed to display insecure content from http://localhost:8000/auth/user
I've consulted the Internet but no one seems to be getting the same error message. Consulting a friend, it seems as if I have to https secure my backend, and futher researching the subject, it seems that there is no free way to upload a SSL/TSL certificate (reference: heroku: set SSL certificates on Free Plan?). Is there a solution to this?
Silly me, really. Turns out, localhost:8000 refers to the computer of the user. https://lyrics-chords.herokuapp.com/ is the server for both the backend and frontend, so updating the backend end URL calls sufficed.

Djstripe - Stripe webhook 404 error: how to resolve?

For my Django project, I am using djstripe. Using test data, I have confirmed that payments are successful. However, when testing a webhook, I get errors of 404 and then it sometimes changes to 503 (for the same webhook). I am using Heroku free tier so I am not sure if that is the problem, or if I am configuring the webhooks entirely wrong (likely since this is my first project). Any help is appreciated.
Stripe endpoint I have as [heroku domain]/users/accounts/webhook/ and my project urls is path('users/accounts/', include('allauth.urls')),
404 means that the URL you've provided to Stripe for your webhook is not found on/by your server; this is something you'll need to investigate on your end.
If you share more code - like specifically the code containing your route for the webhook - that might be useful for helping you diagnose the issue here.
i have found some solutions.
1- copy response of HTML tags and convert it to an HTML Page. you will be able to see the error raising from your platform which is failing the webhook.
2- Debug the each line of webhook view/code.

Django: security middleware is crashing the site

On production, I've been trying to add the djangosecure.middleware.SecurityMiddleware (from http://pypi.python.org/pypi/django-secure)to my settings, but haven't had any luck making it work.
When I run:
./manage.py checksecure
Everything passes perfectly fine. But I'm unable to load the site up. It gives me the following error:
The webpage has resulted in too many redirects. Clearing your cookies for this site or
allowing third-party cookies may fix the problem. If not, it is possibly a server
configuration issue and not a problem with your computer.
Locally, when I use the production settings I receive a page error with:
Unable to make a secure connection to the server. This may be a problem with the server,
or it may be requiring a client authentication certificate that you don't have.
My terminal then gets filled with strange errors that I can't decipher:
[12/Jan/2013 14:15:25] code 400, message Bad HTTP/0.9 request type

Any advice?
Infinite-redirects means you have set SECURE_SSL_REDIRECT to True, but in production your site runs behind an SSL-stripping proxy server, so Django can't tell that the request is already in fact SSL, so it continually tries to redirect to SSL. As noted in the linked docs, you need to figure out what header your proxy sets to indicate an externally-SSL request, and set the SECURE_PROXY_SSL_HEADER setting accordingly.
Using the production settings locally will not work because Django's development server does not support SSL. The strange terminal output is your browser trying to make an SSL handshake with a server that doesn't understand SSL.

Catching Django Errors When Client Is Not A Web Browser?

I'm building a Django web service that is called from an application. When it throws an exception, I can't see the Django debug page, and can't get to it because the calling application doesn't behave like a web browser (and I don't have control over that application).
Is there a way to redirect the Django error page to a a log file rather than to the calling client, possibly via changing the FastCGI config (I'm using lighty + FastCGI)? Or maybe a "dump to file" config option or some sort of LogExceptionToFile() method within the framework itself?
You might try just creating custom ExceptionMiddleware. Just change the process_exception method to log the exception and request data somewhere.
Here's an example: http://www.peterbe.com/plog/who-was-logged-in-during-a-django-exception
If the exception in the django app is not caught, and DEBUG = True, then the exception should be sent to the client.
Some options to help you get debugging info:
Enable and configure logging
Set up email error reporting
Use something like Wireshark to inspect the HTTP request and responses.
