Cannot connect to the Ispconfig panel with the "admin" and "admin" connection parameters

[chegmarco1989]

Hello.

We have successfully installed ispconfig on a DigitalOcean - Ubuntu 18.04 Droplet. See the following screenshot: https://ibb.co/TYpBb5P.
But the concern is that after installation, we do not have access to the ispconfig dashboard when we enter the connection information namely "admin" as username and password as it is recommended just after the success of the installing ispconfig, we get an error saying "Username or Password wrong". You can see it on the 2nd screenshot below: https://ibb.co/nk4X9sd.

NB: When we even try to access the directory: "/var/lib/roundcube/plugins/ispconfig3_account/config/" to manually modify the ispconfig panel connection information in the "config.inc.php" file , we get another error saying that this directory does not exist.

Thank you for helping us please.
