I've been looking everywhere but cannot seem to find anyone with my same problem. Here's my situation...
Django App: Running on Centos7 Vagrant guest 10.0.0.2 connecting to DB
Postgresql-10 DB: Running on Centos7 Vagrant guest 10.0.0.1 serving the Django app, also has pgAdmin4 running on it
When I bring these vagrant machines up they are able to initially connect. I notice when I leave them idle for periods of time then the Django app cannot connect any longer to the DB. Even weirder, most of the time, but not all the time, I simply needed to restart the postgresql database service and it would be able to connect again. Right now that's not even the case so I can no longer ignore this problem by just restarting the DB service.
Any ideas on what could be going on here? I've tried a couple things but nothing seems to work. My feeling is it's something on the database machine causing issues since like I said usually this just required a simple restart of the DB service to fix.
I'm completely confused by how it just loses connection sometimes randomly.
Below is the error that is printed out when I try to restart the django app and run "python3 manage.py makemigrations"

What should I do to fix this and use CVAT?
My Ubuntu version: Ubuntu 22.04.1 LTS
I thought adding Django's authentication system might solve it so I did pip install django-auth but it changed nothing
I have had the same problem but I found a solution. Some user suggested a problem with docker installation here. My way to solve it is:
Remove docker installation completely. This can help.
Install docker from the atp repository:
sudo apt install containerd
sudo apt install docker.io
Do everything as in the CVAT installation guide, but ignore the part about installing Docker and use the commands above. With this solution some comands indicated in the installation guide will require sudo. In the guide:
Instead of docker compose up -d use sudo docker-compose up -d
Run with sudo docker-compose up

django.db.utils.OperationalError
I modified only this base.py part, but the "migrate" command is not executed and an error occurs. What is the reason?
installed postgresql
create DB name as "instagram"
installed cookiecutter
modified "base.py"
run "py manage.py makemigrations"
error occured
Now I'm using postgresql version 15, could it be the reason of error?
Because I tried to use version 14 also but have same error.
Remove all the migration files, then:
python manage.py makemigrations
python manage.py migrate
I am trying to host my website on digitaloceans. on running
python manage.py makeigrations
I get these errors

django.db.utils.OperationalError: FATAL: password authentication failed for user "djangoadmin"
FATAL: password authentication failed for user "djangoadmin"
djangoadmin is not in my database at all. I am using Postgresql as my database
However, django admin is an ssh user.
Django database settings:
DATABASES = { 'default':
{ 'ENGINE': 'django.db.backends.postgresql',
'NAME': env.str('NAME'),
'USER': env.str('USER'),
'PASSWORD': env.str('PASSWORD'),
'HOST': 'localhost',
'PORT': '5432', } }
What can I do please? I have reset the password. I have dropped and created a new table. I keep getting this error
I deleted my postgresql database from pgAdmin III (right click on databases/mydatabase => delete/drop).
Now I want start anew and make the first migration that should create the database but instead it give an error: database don't exist.
Until now I was using sqlite3 and this procedure worked.
What I should do?

First migration doesn't create the database, it needs existing database to create tables in it.
To create postgres database run from your terminal:
createdb -U postgres possedimenti_database
You might have to replace postgres in above command with your database user.
check the details in your settings.py for your DB. Recreate the PostgreSQL database using those exact same details (port number, user, host, password etc). Try this existing solution here link here:
PostgreSQL - create a new DB through pgAdmin UI in order to create the DB via pgAdmin
