use nginx and mysql and install phpmyadmin with apache2 in ubuntu vps
site work great and have no problem while phpmyadmin error connection timeout
for example can reach with xx.xx.xx.xx to site but can not reach phpmyadmin with xx.xx.xx.xx/phpmyadmin

here is my nginx config

    listen 80;
    listen [::]:80;
    server_name localhost;
    root /var/www/html;

    add_header X-Frame-Options "SAMEORIGIN";
