I installed nextcloud in a dedicated Raspberry and everything works correctly.
I only have one problem:
The mail server does not work (for sending notifications and password recovery).
I set all the parameters correctly (used in other occurrences) but the error message is:
There was a problem sending the email. Check your settings. (Error: Connection could not be established with host smtps.aruba.it [# 0] Log data: ++ Starting Swift_SmtpTransport !! Connection could not be established with host smtps.aruba.it [# 0] (code: 0))
I attach the screen.
Do I have to configure anything else to enable the Raspberry?
Thanks in advance for the help
