Я настроил сервер для размещения нескольких веб-сайтов в соответствии с этим руководством: https://blog.ssdnodes.com/blog/host-multiple-ssl-websites-docker-nginx/
Я также настроил docker -compose.yml для WordPress, как они это сделали в примере 2 в том же учебнике. Но когда я открываю веб-сайт, я получаю сообщение об ошибке «Ошибка при установлении соединения с базой данных». Я помню, как делал это несколько месяцев назад, когда все работало нормально, но я не могу вспомнить, что я сделал по-другому.
Это сообщение об ошибке, которое я получаю (несколько раз) после ввода docker -compose up
wp_test | MySQL Connection Error: (1045) Access denied for user 'wordpress'@'172.20.0.9' (using password: YES)

Я попытался остановить и запустить изображение, как предложено здесь: https://www.reddit.com/r/docker/comments/ahzv5d/wordpress_cant_connect_to_mysql/
Я также попробовал другой wordpress docker -config.yml и добавил nginx paramaters myselve, но получил то же сообщение об ошибке https://docs.docker.com/compose/wordpress/
РЕДАКТИРОВАТЬ Я получил новые сообщения об ошибках
