[traefik] No change on login after the initial deploy

[IoannisKonstatinopoulos]

Describe the bug
After installing the self-hosted version of CISO-assistant and creating the user for first login, we receive at first an error { detail: "Not Found" } and then multiple times the another error SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON .
The above errors are triggered every time i try to login inside, and the login screen never changes. it's like i'm just getting the error.
Same error as can be viewed below, through inspect.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://ciso.sample.dev/login?next=/'
2. Give login credentials as created - according to documentation.
3. Click on 'login'

Expected behavior
Login to service.
