I encountered this error after deploying the project on a Linux server. But when running it on localhost, I had no error like this in addition that I say, I have a blog application

Django User Login Issue

I am back again with a Django Question. I am having issues with getting my login screen to work. I feel like maybe this is a simple issue that I am just not seeing. I am using the current versions of Python and Django. I am getting a NoReverseMatch error when trying to access my login page. Here is the code, along with some screen shots:
base.html:
<p>
Learning Log -
Topics -
{% if user.is_authenticated %}
Hello, {{ user.username }}.
{% else %}
log in
{% endif %}
</p>
{% block content %}{% endblock content %}
login.html:
{% extends "learning_logs/base.html" %}
{% block content %}
{% if form.errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}
<form method="post" action="{% url 'users:login' %}">
{% csrf_token %}
{{ form.as_p }}
<button name="submit">log in</button>
<input type="hidden" name="next" value="{% url 'learning_logs:index' %}"/>
</form>
{% endblock content %}
users/urls.py:
from django.urls import path
from django.conf.urls import url
from django.contrib.auth.views import LoginView
from . import views
app_name = 'users'
urlpatterns = [
# Login page
#path('login/', LoginView, {'template_name': 'users/login.html'}, name='login'),
path('login/', LoginView.as_view(template_name='users/login.html')),
]

Error message

Since you commented out the name='login' part. Django can no longer find a path(…) [Django-doc] with that name hence the error.
You should add the name=… parameter:
# users/urls.py
from django.urls import path
from django.contrib.auth.views import LoginView
from . import views
app_name = 'users'
urlpatterns = [
# Login page
path(
'login/',
LoginView.as_view(template_name='users/login.html'),
name='login' # name of the path
),
]

When we extend an allauth view and create a new url based on that view is the old "/accounts/*" URLs of django allauth still required?

I extended the SignupView of django-allauth and created a url "/account-signup/" and also some minor changes in the template and I'm using the url name of my url. So, it keeps showing error that:
NoReverseMatch at /account-signup/
Reverse for 'account_login' not found. 'account_login' is not a valid view function or pattern name.
I've tried searching where the url name account_login is used in the template. Also, I've tried enabling the default URLs given by django allauth. It doesnt show error when the allauth URLs are included in the urls.py file.

{% extends "account/base.html" %}

Problem with ERR_TOO_MANY_REDIRECTS django 2.1

I started to create login module in django. Login module is ok but I have problem with logout. When i click Logout - we see "error -ERR_TOO_MANY_REDIRECTS"
Probably something in this file is incorect: account/urls.py
from django.conf.urls import url
from django.urls import path
from django.contrib.auth import views as auth_views
from . import views
app_name = 'account'
urlpatterns = [
path('', auth_views.LoginView.as_view(template_name='account/login.html'), name='login'),
path('logout/', auth_views.LogoutView.as_view(template_name='registration/logout.html'), name='logout'),
path('logout-then-login/', auth_views.logout_then_login, name='logout_then_login'),
path('dashboard/', views.dashboard, name='dashboard'),
base.html
<body>
<div id="header">
{% if request.user.is_authenticated %}
<ul class="menu">
<li {% if section == "dashboard" %} class="selected"{% endif %}>

</li>
<li {% if section == "images" %} class="selected"{% endif %}>
Obrazy
</li>
<li {% if section == "people" %} class="selected"{% endif %}>

</li>
</ul>
{% endif %}
<span class="user">
{% if request.user.is_authenticated %}
Witaj, {{ request.user.first_name }}
Wyloguj
{% else %}
Zaloguj
{% endif %}
</span>
</div>
<div id="content">

</div>
</body>
logout.html
{% extends "base.html" %}
{% block title %} Wylogowanie {% endblock %}
{% block content %}
<h1>Wylogowanie</h1>
<p>Zostales wylogowany. Mozesz
zalogowac sie ponownie</p>
{% endblock %}
settings.html
...
LOGIN_REDIRECT_URL = reverse_lazy('account:dashboard')
LOGIN_URL = reverse_lazy('account:login')
LOGOUT_REDIRECT_URL = reverse_lazy('account:logout')
show error

You've set LOGOUT_REDIRECT_URL to point back to the LogoutView which will cause a redirect loop. The LOGOUT_REDIRECT_URL should point to a URL that the user will be redirected to after they've logged out using the LogoutView.
Setting LOGOUT_REDIRECT_URL will override any template that's been set. Since you've explicitly set a template for the LogoutView in your urls.py, you should remove LOGOUT_REDIRECT_URL from your settings which will allow the template to be rendered.

Error: 'login' not found. 'login' is not a valid view function or pattern name

This is the first time I am using Django login template and I ran into a problem. It keeps saying that login is not a valid view function but I define it in the urls.py in my users app:
Not sure what I am doing wrong.
main urls.py
urlpatterns = [
path('', include('blogging_logs.urls', namespace='blogging_logs')),
path('users/', include('users.urls', namespace='users')),
path('admin/', admin.site.urls),
]
app: blogging_logs: base.html
<p>
Home
Categories
{% if user.is_authenticated %}
Hello, {{ user.username }}.
{% else %}
login in
{% endif %}
</p>
{% block content %}{% endblock content %}
app: users: urls.py
from django.contrib import admin
from django.urls import re_path, path
from django.contrib.auth import authenticate, login
from django.contrib.auth import views as auth_views
app_name = 'users'
urlpatterns = [
# Login Page
path('login/', auth_views.LoginView.as_view(template_name='login.html')),
]
app:users: login.html
{% extends "blogging_logs/base.html" %}
{% block content %}
{% if form.errors %}
<p>Your username and password din't match. Please try again.</p>
{% endif %}
<form class="" method="post" action="{% url 'users:login' %}" >
{% csrf_token %}
{{ form.as_p }}
<button name='submit'> Login in </button>
<input type="hidden" name="next" value="{% url 'blogging_logs:index' %}" />
</form>
{% endblock content %}

You are missing the name argument for the path function:
Change the following line
path('login/', auth_views.LoginView.as_view(template_name='login.html')),
to
path('login/', auth_views.LoginView.as_view(template_name='login.html'), name='login'),
