Hi, I can't set account for @vivaldi.net mailbox. I've tried POP3 and IMAP, but to no avail.

Hidden Text

I tried these    POP3: pop3.vivaldi.net,        Port: 110,        Authentication method: normal password,        Connection security: STARTTLS    IMAP: imap.vivaldi.net,        Port: 143,        Authentication method: normal password,        Connection security: STARTTLS …or, instead, one of the two, below:    POP3s: pop3.vivaldi.net,        Port: 995,        Authentication method: normal password,        Connection security: SSL/TLS    IMAPs: imap.vivaldi.net,        Port: 993,        Authentication method: normal password,        Connection security: SSL/TLS To send e-mails, set the server, below (Outgoing server):    SMTP: smtp.vivaldi.net,        Port: 587,        Authentication method: normal password,        Connection security: STARTTLS

Every time I try to connect from The Bat (11.4.3), I get the following log message:
FETCH - Il server riporta un errore. La risposta è: -ERR [AUTH] Your account does not have permission to access mail services

Does anyone know if there are any other settings to configure (perhaps on the website, but I haven't found them)?
Thanks
