Django doesn't set cookie

I have a problem setting cookies in Django.

Basically I have 3 different cookie I wanna set:

  1. Session ID
  2. Access token
  3. Refresh token

For some reason Access and Refresh tokens are set, but the Session ID (SSID) doesn't set. If I change key of "SSID" to for example "TEST_COOKIE" it passes and I can see it in dev tools. However I need SSID and for some magical reason it doesn't work.

Here's example of my code:

class AuthResponse(SuccessResponse):
    def __init__(self, data={}, ssid='', access_token: str = '', refresh_token: str = '', **kwargs):
        super().__init__(data, **kwargs)


        if access_token:
        if refresh_token:

AuthResponse inherits from SuccessResponse which is based on DjangoJsonResponse, and DjangoJsonResponse eventually inherits from HttpResponse.

So the question is - what could cause of getting rid of "SSID" cookie?

I tried to look around and find if all the data appears in init function and apprently eveyrthing is fine. All data, ssid, access_token and refresh_token come through, but only "SSID" doesn't get set.

As well I tried to use "httponly" and "secure" while setting cookies, but it didn't help.

There was an idea that might be middleware affects somehow on this, however I don't know who to check this out...

Is there anyone familiar with this who can potentially make an advice of why is this happening?

Thanks in advance!

I found the answer while working on localhost the SESSION_COOKIE_DOMAIN should not be used, so I made it in this way in

if website_settings.current_instance != 'dev':
        if website_settings.session_cookie_domain
        else f".{SITE_DOMAIN}"

This way it saves all needed cookies and browser sees them.
