Unable to select database

We were able to connect to the MySQL database server (which means your username and password are okay) but not able to select the database.

The MySQL error was: Lost connection to MySQL server during query.

Currently, the database is polyusnet_dru2. The username is polyusnet_dru2 and the database server is localhost.

• Are you sure you have the correct database name?
• Are you sure the database exists?
• Are you sure the username has permission to access the database?
