Mysqli Connection Refused

[MikeiLL]

This is the second implementation of this docker setup on this computer. The other instance is down.

Using Docker v2.3.0.2.

Getting the following error when wordpress tries to connect to the DB:

wordpress_1  | [29-Jun-2020 16:21:05 UTC] PHP Warning:  mysqli::__construct(): (HY000/2002): Connection refused in Standard input code on line 22
wordpress_1  | MySQL Connection Error: (2002) Connection refused

I tried adding a port number in the docker-compose file:

WORDPRESS_DB_HOST: "mysql:3306"

Which makes no difference as 3306 is the default:

CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS              PORTS                NAMES

Based on this SO post, I have tried

• restart Docker
• rundocker restart wordpress
• add restart: unless-stopped to both wordpress and mariadb services.

Same error. Any ideas?

Additionally the following notice occurs:

wordpress_1  | AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.29.0.4. Set the 'ServerName' directive globally to suppress this message

Never mind. I was going to the wrong url!
