I got this Invalid HTTP_HOST header: '127.0.0.1:8000'. You may need to add '127.0.0.1' to ALLOWED_HOSTS.

FYI - Seems to have no effect on that error.  

From what I see the development server just doesn’t support SSL.

But, here are instructions on setting it up.


I have not yet tested these instructions, and also, I might suggest instead taking a look to see if it’s possible to get Let’s Encrypt to work with Django dev server?

Actually going further, I see:


Which appears to have been updated for Django 3.7 or so, and claims to have no outside dependencies, and a bit clearer documentation?
And describes how it could use a Let’s Encrypt key.  

I’m not sure which one I’m going to try…  But it does seem possible that a dev server can be updated easily to use SSL.

Any reason you want to use HTTPS for your development server?

Why not simply access it through HTTP, ie. http://127.0.0.1:8000/ ?

You shouldn't use the development server for anything other than
development and (in general) only access it through a local host
connection, so there shouldn't really be any reason to use HTTPS.

Kind regards,
