Start by inspecting the Docker Compose configuration alongside the reported docker ps -a output, focusing on the phpmyadmin container and its published port. Reproduce the failure with curl 0.0.0.0:8080 -vvv; the issue is done when phpMyAdmin responds at http://localhost:8080.

docker compose successfully return.
