I have a problem during adding facebook login button to my website at localhost.
I've already add mysite.com to hosts file and installed django-extensions, werkzeug, pyOpenSSL. By running command python manage.py runserver_plus --cert-file cert.crt my own-made sertificate was created. I imported this certificate to Trusted Chrome sertificates but safe connection doesn't establish. When i pass https://example.com:8000/account/login/ I hit an error NET::ERR_CERT_COMMON_NAME_INVALID,
Failed to confirm that this is the server example.com. Its safety certificate refers to *. The server may be configured incorrectly or someone is trying to intercept your data.
Please help me to solve this.

I am new to Django.
I was trying to launch "NewsBlur" (Django based) to my local PC , when everything is set.
I ran "python3 manage.py runserver" . Whenever I tried to click btn or manually trigger http request I got error below on my server:
The host 127.0.0.1:8000 does not belong to the domain example.com, unable to identify the subdomain for this request
Anything I incorrectly configured in django ?
My [settings.py][2]
When using the django.contrib.sites framework, the first site is installed with domain name 'example.com', using:
A management utility
Which is then hooked into migrations
You can open the Django admin if it is made available and go to the "sites" app, then change the domain name of the site. Or you can connect to the PostgreSQL database and change the row, which will be in the django_site table.
I have a google appengine project running in localhost. Everything works fine until i go to the 'login' page. When i go there i get the following error:
This site can’t provide a secure connection 127.0.0.1 sent an invalid response.
Try running Windows Network Diagnostics.
ERR_SSL_PROTOCOL_ERROR
the appengine command i use to run the project is dev_appserver.py" --host 127.0.0.1 . This is run pycharm. This only occurs in the 'login' endpoint and no other endpoint.
The console error i get is:
default: "GET /signin HTTP/1.1" 301 -
to connect over HTTPS you need a valid SSL certificate on your server here is you local server as I understand from the message. you can get a certificate for your local server but I don't think it's worth the trouble while working locally. On the other hand when you deploy to Google App Engine, you get SSL certificate automatically and it's managed by Google, that's why your code works without any problem in the deployment.
I have built a Flask-Socketio server application which works as expected when I connect to it using a javascript client via ws, but fails to connect via wss, both on localhost and when running on my Digital Ocean server. With wss, I get this error in the console (client running on Heroku):
index.js:14 WebSocket connection to 'wss://[IP_ADDRESS]/socket.io/?
EIO=3&transport=websocket' failed: Error in connection establishment:
net::ERR_CONNECTION_REFUSED
When the client is running on localhost, it causes this error:
polling-xhr.js:265 GET https://localhost:5000/socket.io/?
EIO=3&transport=polling&t=MW6p0Aj net::ERR_SSL_PROTOCOL_ERROR
The flask server is running with
socketio.run(app, host='0.0.0.0', port=443) # production
or
socketio.run(app, host="localhost", port=5000) # localhost
At first I thought it could have been an issue with the Nginx configuration or server ports not being open, however the same issue occurs with the server running on Localhost, so now I'm suspecting an issue with my Flask-Socketio application
Turns out I didn't have SSL certificates configured. I followed the instructions in this guide to create a self-signed SSL certificate and configure Nginx to use it. Now works as expected.
There are lot of issues with Flask-Socketio. With Apache server it almost doesn't works.But you are using Nginx. Refer following link on github.

I just tried to set up TLS on a django app hosted by Heroku PaaS. How can I verify if TLS was configured properly and that the communication is encrypted?
I tried:
curl -vI https://www.example.com
but I cannot tell if it is properly configured.
I tried:
heroku certs:info --app Appname
and it says
appname has no SSL certificates
If not set up properly but if I go to the url using chrome, I get the padlock symbol followed by 'secure'. What is going on? xD
This is probably a very basic question. I SSH to my virtual Ubuntu server and start a django webserver running on localhost:
Downloading/unpacking django
Downloading Django-1.9.5-py2.py3-none-any.whl (6.6MB): 6.6MB downloaded
Installing collected packages: django
Successfully installed django

You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.

Django version 1.9.5, using settings 'mysite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
The Ubuntu server has a static IP [x.xxx.xxx.xxx] so from another machine on another network I try to access the above website in a browser using that static IP address:
x.xxx.xxx.xxx:8000
But I get:
This site can’t be reached
x.xxx.xxx.xxx refused to connect.
ERR_CONNECTION_REFUSED
So I assume that I cannot access the website like this and that is only available on the host it self even though the host has an external/static IP address?
Edit:
The answer is also in:
https://docs.djangoproject.com/en/1.9/intro/tutorial01/#the-development-server
python manage.py runserver 0.0.0.0:8000
You need to run your web server on 0.0.0.0:8000, then externally you would use either ip or host name to access. Using 0.0.0.0 means the django service would listen to all configured network interfaces.
Check wikipedia on details about 0.0.0.0.
Another answer on serverfault could be helpful.
