Django.db.utils.operationalerror: (2026, ‘ssl connection error: unknown error number’)

Error: django.db.utils.OperationalError: (2026, ‘SSL connection error: unknown error number’)

Explanation: This error occurs when there is an issue with the SSL connection while trying to connect to the database.

Solution: To resolve this issue, you can try the following steps:

1. First, verify that you have the correct SSL settings configured in your Django settings file. Make sure the ‘OPTIONS’ key in your ‘DATABASES’ setting includes the ‘sslmode’ and ‘sslrootcert’ options if required by your database.
2. Check if the SSL certificate used by the database server is valid and not expired. If necessary, renew or update the SSL certificate.
3. Ensure that the database server is running and accessible. Double-check the host, port, and other connection details.
4. If you are using a self-signed SSL certificate, make sure to add it to your server’s trusted CA certificate list. Otherwise, you may need to obtain a valid SSL certificate from a trusted certificate authority.
5. If none of the above steps solve the issue, it is possible that the SSL connection is being blocked by a firewall or a proxy. Verify the network settings and make sure the necessary ports are open for the SSL connection.

Here is an example of how your ‘DATABASES’ setting in the Django settings file should include the SSL options:

{
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'mydatabase',
        'USER': 'myuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '5432',
        'OPTIONS': {
            'sslmode': 'require',
            'sslrootcert': '/path/to/certificate.crt',
        },
    }
}
