Database does not connect to server

Question

Hello,
I have odoo running on version 17, but now for another project I need odoo 14. I installed it, but I get the following error:

connection = _connect(dsn, factory_connection=factory_connection, **kwasync)
psycopg2.OperationalError - - -

Does anyone know how I can fix it? I'm new to Odoo, I put both installations on port 5432 and 8069 for http, I tried changing them in case it had something to do with it but I keep getting the same error. And I'm not running both odoo servers at the same t

Hi Rome,
Please recheck the following are correct
1.Password is correctly set.
2.Database user is correctly created as per name in odoo config file.
3.If your password contains white spaces, try with double quotes.
