At a loss. I use Hubspot as a CRM system. Have had my roundcube email system integrated and working for some time. Almost overnight I lost 2 email connections. IMAP settings: Incoming mail.myurl.com port 993 Outgoing mail.myurl.com port 465. I'm using the correct email address and password.
Roundcube is a web based IMAP client not an email service, this question needs to be directed to your email provider.
