postgres server error 500

I’m using django 1.9, gunicorn, nginx and postgres as database for my website. My site is up and running but when i try to login as admin or user i get server error 500 on webpage and on terminal i get “is the server running on host and accepting tcp/ip connections on port 5432”.

I thought there might be a problem in postgres.conf and pg_hba.conf. But there are 2 host all all…one for IPv4 and one for IPv6 in pg_hba.conf.

I can’t figure out how to edit pg_hba.conf. Please use above’s IP to explain.

One more thing will it solve the problem or i might need to do something else?

Did you createsuperuser? Is the dbuser specified in your settings in /etc/postgresql/9.X/main/pg_hba.conf? If so and if server is local to django, try setting password to nothing in settings and the user like this: local databasename databaseuser trust in pg_hba. Reload postgres service postgresql restart and gunicorn service gunicorn restart
