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: Too many connections.

Currently, the database is drupal_main. The username is nrdrip and the database server is 10.100.128.21.

• 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?
