I am trying to configure Nextcloud to use the EMail feature in additional settings, however it keeps returning the following error - A problem occurred while sending the email. Please revise your settings. (Error: Unable to connect with TLS encryption)
I know this isn’t the case as I can log in to the dedicated account using my email client, using IMAP and SMTP. My server requires STARTTLS and I connect on port 587. Not sure why Nextcloud won’t connect.
