I've setup my Django application to use SSL while connecting to the Postgresql database via pgbouncer. I'm using Psycopg2 library. I've done this before successfully, so I just did the same steps again. But! After installing certificates to both servers and clients and making the installations, when I tried to run my application, I've got the error: **django.db.utils.OperationalError: server does not support SSL, but SSL was required** When I entered the command psql --set=sslmode=verify-full -h DBHOST -p DBPORT -U USERNAME DBNAME I can successfully connect to database by entering my password But when I entered the code from python shell import psycopg2 conn = psycopg2.connect(database='DBNAME', user='DBUSER', password='DBPASS', host='DBHOST', port='DBPORT', sslmode='verify-full') I got the stack trace; /virtual_environment_path/local/lib/python2.7/site-packages/psycopg2/__init__.pyc in connect(dsn, connection_factory, cursor_factory, **kwargs) 128 129 dsn = _ext.make_dsn(dsn, **kwargs) --> 130 conn = _connect(dsn, connection_factory=connection_factory, **kwasync) 131 if cursor_factory is not None: 132 conn.cursor_factory = cursor_factory OperationalError: server does not support SSL, but SSL was required What may be the problem? I've compared the installated packages between previous installation which is succesful, versions of packages, certificates, file permissions etc. But I'm stuck in this issue. Thank you very much for your help.
