multi server setup - connection to imap server failed after update to 3.2.2

ispconfig 3.2.2
debian 9 (stretch)
web, mail, 2 x dns, web2, web3 and new test server.
After upgrading to 3.2.2 from 3.1.15p all went well, i generated new cert (i shouldnt have) but i did.
My problem.
roundcube states - connection to imap server failed. the web server connects to mail.tlsystems.co.uk for imap mail.
specific error from /var/log/roundcube/error

Code:

[11-Jan-2021 09:43:43 UTC] PHP Warning:  stream_socket_enable_crypto(): Unable to locate peer certificate CN in /usr/share/roundcube/program/lib/Roundcube/rcube_imap_generic.php on line 1017
[11-Jan-2021 09:43:43 +0000]: <nfpu7nds> IMAP Error: Login failed for [email protected] from 79.79.62.1. Unable to negotiate TLS in /usr/share/roundcube/program/lib/Roundcube/rcube_imap.php on line 193 (POST /webmail/?_task=login&_action=login)

I am not sure whether TLS or SSL security is working.
as on mail server im getting this:

Code:

TLS handshaking: SSL_accept() failed: error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown: SSL alert number 46, session=</>

I havent updated to latest Lets encrypt, as i thought that would be too much change too quick, but if this is the issue or another part of it please let em know.

<b>/etc/roundcube/config.inc.php</b>

Code:

$config = array();
include_once("/etc/roundcube/debian-db-roundcube.php");
$config['default_host'] = 'tls://mail.tlsystems.co.uk';
$config['imap_conn_options'] = array('ssl' => array('verify_peer' => false,'verfify_peer_name' => false,),);
$config['smtp_conn_options'] = array('ssl' => array('verify_peer' => false,'verify_peer_name' => false,),);
$config['smtp_server'] = 'tls://mail.tlsystems.co.uk';
$config['smtp_port'] = 465;
$config['smtp_user'] = '%u';
$config['smtp_pass'] = '%p';
$config['support_url'] = '';
$config['product_name'] = 'Roundcube Webmail';
$config['des_key'] = 'some-key-here';
$config['plugins'] = array(
$config['skin'] = 'larry';
$config['enable_spellcheck'] = true;

 

Just the config.inc.php?

 

I have changed that, im still getting ...

Code:

connection to imap server failed

output from /etc/log/roundcube/error

Code:
