I can't connect to postgresql database in deployment - django

Question

Hello I just want to deploy my django project in python anywhere .... and when I run the command python manage.py migrate
it shows this error message django.db.utils.OperationalError: connection to server at "<Host name>" (<IP address>), port 5432 failed: Connection refused Is the server running on that host and accepting TCP/IP connections?
I think that the problem in python anywhere because when I connect to the server in pgadmin using the same info in the settings.py file I don't get any error messages and you have to know that I am using neon.tech for my postgresql database
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': '<the database>',
'USER':'<User>',
'PASSWORD':'<Password>',
'HOST':'<Host>',
'PORT':5432,
}
}
and I am sure that all information is right because I used it to connect to the server in pgadmin in my local machiene

If you are having trouble connecting to a PostgreSQL database in a deployment environment, there are a few things you can check:
Verify that the database is running: Make sure that the PostgreSQL database is running and accessible from the deployment environment. You can check this by attempting to connect to the database using the 'psql' command-line tool.
Check the connection settings: Ensure that the connection settings in your deployment configuration are correct, including the database host, port, database name, user, and password.
Check firewall settings: If you are connecting to a remote PostgreSQL database, ensure that the necessary firewall ports are open to allow incoming connections to the database server.
Check for network issues: Check for any network issues that may be preventing the deployment environment from connecting to the database. For example, if you are deploying to a virtual private cloud, ensure that the network settings are configured correctly.
Check for authentication issues: Make sure that the user and password specified in the connection settings have the necessary permissions to access the database.
Check logs for errors: Check the logs for any error messages that may indicate the cause of the connection issue.
By investigating the above points, you should be able to narrow down the cause of the connection issue and take the necessary steps to resolve it.
