Problem in connecting with server other than localhost

As my akaunting open source software is properly connected with the localhost and it's work but i am facing trouble when i connect the downloaded version to my online service via webhosting. i change the hostname,database and database prefix of the file config.php but still i am facing trouble in connecting with the server.It's gives me an error at the second stage database setup (Error: Could not connect to the database! Please, make sure the details are correct).Is there an thing which i am not changing in files is any one here who can help me as i am waisting too much of my time.

Hello,

You should not change the config.php but .env file in the root directory of Akaunting installation.
