Hello everyone,
please help me to understand the problem of installation Nextcloud 20 + MariaDB.
I’ve got the following docker-compose file:

services:
reverse-proxy:

When I kick off the containers, Nextcloud shows this in its logs:

At the same time, there are no problems with Wordpress - it works with its database normally.
What is the root of the problem and how to fix it?
