I recently started using sql and connected to an remote sql server. I can run queries on it in python shell and get correct results. However, when I run
manage.py runserver
It tells me that there I need to migrate, however when I migrate I get an error saying:

What should I do to fix this error.

So this is a networking problem in which your application is unable to establish a TCP connection to your database. Maybe because of a lack of configuration on your RDS instance? wrong hostname? wrong port? firewall (as mentioned by #Willem van Onsem)? Maybe the Amazon AWS guide on connecting to their database service helps you
In any case it has nothing to do with your program code, apart from the connection string if its wrong.
Im having an odd problem when trying to run my website on my local machine. If I type in python manage.py runserver, I get the following error and my site won't load.
I tried to restart my Postgres database on my local machine and restarted the computer but having the same problems.
My site is built in Python/Django hosted on Heroku with files served via Cloudfront/AWS.
