I recently finished my django project and i switched my database from the local SQLite database, provided by django, to an online postgreSQL database provided by elephantSQL. Clearly, by entering my database credential in the setings.py file of my django project i am able to migrate to my new database locally while not on my host's bash console. Meaning that, when i run my server on port 8000 it loads my data from the postgreSQL, but when i push my website to PythonAnywhere and try to run my migrations from the bash console of PythonAnywhere it throws out the following error:`
django.db.utils.OperationalError: connection to server at "'USER'.db.elephantsql.com" ("DATABASE_IP"), port 5432 failed: Connection refused
Is the server running on that host and accepting TCP/IP connections?
`
I even changed my database Host from elephanSQL to nhost, but still it promps the same result.

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.
I am following this tutorial to upload my existing Django project running locally on sqlite to Google Cloud Run / Postgres.
I have the cloud_sql_proxy service running and can sign into Postgres from the command line.
I am at the point of running the command
python manage.py migrate
And I get the error:
django.db.utils.OperationalError: connection to server on socket "/cloudsql/cgps-registration-2:us-central-1:cgps-reg-2-postgre-sql/.s.PGSQL.5432" failed: No such file or directory
Is the server running locally and accepting connections on that socket?
The answer to that questions is Yes, the server is running locally and accepting connections because I can log in with the Postgres client:
agerson#agersons-iMac ~ % psql "sslmode=disable dbname=postgres user=postgres hostaddr=127.0.0.1"
Password for user postgres:
psql (14.1, server 13.4)
Type "help" for help.
postgres=>
I double checked the connection string in my .env file and it has the correct UN / P
Is this scoket not getting created somehow in a previous step?
/cloudsql/cgps-registration-2:us-central-1:cgps-reg-2-postgre-sql/.s.PGSQL.5432
It looks like there's a mismatch between what the app is looking for and how you're launching the proxy. The error explains the problem.
You're launching the proxy like this with an incorrect region name (us-central):
cloud_sql_proxy -instances="cgps-registration-2:us-central:cgps-reg-2-postgre-sql=tcp:5432
But the app is looking for us-central1. Try this (omitting the =tcp:5432 to create a Unix socket):
cloud_sql_proxy -instances="cgps-registration-2:us-central1:cgps-reg-2-postgre-sql
So I was trying to host my first Django app on heroku.
Took help form some Youtube channels. I used postgresql as my database. Now when I tried hosting my app on heroku the following error is showing up:
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?```
**This is the error showing**
run postgres -D /usr/local/var/postgres The result of this should be:
FATAL: lock file "postmaster.pid" already exists
HINT: Is another postmaster (PID 379) running in data directory
"/usr/local/var/postgres"?
Then type kill -9 PID in HINT
Let me know if this works for you?
I am trying to deploy my django project to a unix server. When I run the command to create the PostgreSQL database using SSH, I encounter the following error:
$ createdb elections
createdb: could not connect to database template1: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Does the error mean running 'locally' as in the server or my machine?
What is stopping it from connecting to the server?
How do I fix the error?
I'm trying to run a django migration to update my database, but "manage.py migrate" can't connect to my postgresql db. The odd thing is: my django website (which is exactly the same code) is working including connecting to the db.
Error messages:
psycopg2.OperationalError: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.xxxxxx"?
and
django.db.utils.OperationalError: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL
Workaround: Change HOST variable to either localhost or 127.0.0.1 .
