@alkane7 It may be caused by several reasons. I can only list a few here according to my limited experience. If none of them works, you may consult TA or SA at lab class.

  1. Database connection configuration at application.yml is incorrect or your user do not have enough privileges.
  2. Forgetting to release connections or similar resources. The HikariPool is limited to 10 connections.
  3. Your created database has a smaller connection limitation.

@alkane7 If you still have this error, you may continue to discuss this framework issue in discussion #83 together with other students with similar problems.
