ACCEPTED ANSWER

Score 297

The error log is straightforward. As it suggested,You need to add 198.211.99.20 to your ALLOWED_HOSTS setting.

In your project settings.py file,set ALLOWED_HOSTS like this :

ALLOWED_HOSTS = ['198.211.99.20', 'localhost', '127.0.0.1']

For further reading read from here.

settings.py

ALLOWED_HOSTS = ['*'] # if you are in dev or docker

Don't do this in production if you are not using docker, just put the IP address.

if no other answer work you can try modifying manage.py and add this three lines

from django.utils.regex_helper import _lazy_re_compile
import django.http.request
django.http.request.host_validation_re = _lazy_re_compile(r"[a-zA-z0-9.:]*")

to end up having something like this:

import os
import sys

from django.utils.regex_helper import _lazy_re_compile
import django.http.request    
django.http.request.host_validation_re = _lazy_re_compile(r"[a-zA-z0-9.:]*")

def main():
    """Run administrative tasks."""
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project01.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

as it is explained in this post: How to Solve "The domain name provided is not valid according to RFC 1034/1035" in Django during Development
