SSL MySQL remote server (phpmyadmin)

Hi all,
On a multi-server setup when I access PHPMyAdmin (it is installed with ssl under my main server which holds just the control panel of ISPconfig) and login to any of my servers (got a list with a few) I'm getting on the right side:

Server connection: SSL is not being used

The relevant docs saying:

I'm not sure what's the next steps. Do I need to create with certbot SSLs on all my DB servers and configure the MySQL or I shall just add the relevant SSL entry in PHPMyAdmin config?

If anyone has a working PHPMyAdmin config with the SSL enabled will be very much appreciated.

Am I understanding correct that I need to replace all entries in my config that have
$cfg['Servers'][$i]['host']
with:
$cfg['Servers'][$i]['ssl']['host'] etc?

Thanks in advance

 

Further to my post I tried by adding:

PHP:

    //$cfg['Servers'][$i]['ssl'] = true;
    //$cfg['Servers'][$i]['key'] = '/etc/letsencrypt/live/controlpanel.mydomain.com/fullchain.pem';
    //$cfg['Servers'][$i]['cert'] = '/etc/letsencrypt/live/controlpanel.mydomain.com/privkey.pem';

to my config file but with the above in the config it doesn't work at all (can't login).
Under mysql logs there is no error.

Any help is very much appreciated.
