I guess the MySQL DB is rejecting the connection because it has too many. You might want to raise the number of connections. That’s part of the MySQL configuration, so check how can you do that in MySQL

On a Ubuntu system you can run mysqladmin processlist to analyse the connections to the DB (an the DB host with MariaDB/MySQL).
