Bad Request (400) request on working custom domain server

We have a working app deployed to our app domain https://vingineers-demo.azurewebsites.net/

We have set up the custom domain and loaded all of the SSL certificates, pointed the dns to https://sni.demo.vingineers.com

However, we are only getting "Bad Request (400)" from this HTTPs://demo.vingineers.com

All of our Azure configurations / front ends / debugs now say that it is working properly but we can't figure out what is causing this to fail.

Any support would be greatly appreciated!

    Eventually found the anser:

    Our Django server did not have the new domain in "ALLOWED_HOSTS" in settings.py.

    I found this by doing other searching until this came up.

    Normally we would have seen the warning for this, but the switch to a production mode caused us to miss the error!

    Thanks for everyone's input.

    Error 400 says that the request could not be understood by the server due to a syntax issue in the code used for the application. For code based on Node js environment value to address this issue can be set as NODE_OPTIONS with the value with the size you want set on your app. You may check in similar way for your code used
