Context:
VPS -> Cloudron -> LAMP -> PhpMyAdmin (php_version 8.1 / PhpMyAdmin 5.2.1)
Problem:
in phpmyadmin -> "Server connection: SSL is not being used "
I try to get into config.inc.php by terminal of the app with
nano config.inc.php
and add this
$cfg['Servers'][$i]['ssl'] = true;
$cfg['Servers'][$i]['ssl_verify'] = false; // If the certificate is self-signed
$cfg['Servers'][$i]['ssl_ca'] = 'ca-cert.pem';
$cfg['Servers'][$i]['ssl_cert'] = 'server-cert.pem';
$cfg['Servers'][$i]['ssl_key'] = 'server-key.pem';
I know cloudron has no writable database, so I create a new volume and mount it as 777 (read and write).
But still not working. I'm out of idea, energy and skills... 
-> Is someone know documentation, forum topics or just help me ?
Thanks for this incredible app, named cloudron, you guys rock.
