Coolify MySQL Problem Solved | Fix PHPMyAdmin Connection Error (Docker Network Fix)
Overview of the Problem
When running WordPress with MySQL in one container and PHPMyAdmin in another, users often encounter an error preventing them from accessing the database
. The source explains that this is primarily a network issue; Coolify auto-generates separate networks for different services, and because the containers are on different networks, they cannot communicate

The Technical Solution
The video demonstrates a step-by-step process to link these containers:
Identify Network Names: Using a terminal (like Putty), the creator uses Docker commands to list the running containers and their specific network IDs
.
Locate the Target Network: Each service in Coolify has a unique, auto-generated network name (such as strings like ZRW or 12G)
.
Dashboard Configuration: You must navigate to the PHPMyAdmin settings in the Coolify dashboard and edit the configuration
.
Code Injection: The fix involves adding approximately five lines of network configuration code to the PHPMyAdmin service, manually specifying the network name used by the MySQL container
.
Verification: After restarting the container, the terminal will show that PHPMyAdmin is now connected to multiple networks, including the one used by the database
.
Final Result
By synchronizing the networks, the PHPMyAdmin dashboard becomes fully functional
. The user can then log in using their standard database username and password to manage their data successfully
