I know this has been asked a bunch of times here, but none of the suggested solutions seem to work for me. I'm trying to run my Django project from home, and get it to connect to the MySQL db I set up on Python Anywhere, so I set up my database as follows in settings.py:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'samscheding1$scheding_db',
'USER': 'samscheding1',
'PASSWORD': 'secret',
'HOST': 'samscheding1.mysql.pythonanywhere-services.com',
'PORT': '3306',
}
}
However, now when I run python3 manage.py runserver my terminal hangs for around a minute (I assume it's trying to connect to the remote db) and then spits out the following exception:
django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on 'samscheding1.mysql.pythonanywhere-services.com' (110)")
I tried running python3 manage.py makemigrations in case it was failing due to a mismatch with the models vs tables, but I get the same behaviour as runserver. I'll include the full stack trace in case it helps:
(env) $ python3 manage.py runserver
