HELP- (1226, "User '' has exceeded the 'max_user_connections' resource

(1226, "User '' has exceeded the 'max_user_connections' resource

Exceeded the limit after running queries on the workbench and crashed my entire application.

How to solve this problem? Furthermore, it is very slow to access the schema

Your 'max_user_connections' is related to the number of web workers on your plan, so it is possible to increase it by upgrading. However, you should first make sure that your application is properly closing database connections.
