How to increase timeout in debian 10 Mariadb service?

Question

Debian

When my service connects to the database in mariadb, sometimes an error message is displayed that it was not possible to connect to the database (timeout) and when I completely kill the service process in debian 10 and restart everything falls into place, what should I do?
