- Plesk for Linux
Error occurs while trying to connect to add mail account to a mobile device:
Cannot connect to server; Certificate error
Wrong encryption specified in account configuration in mobile.
Use SSL/TLS (Accept all certificates) encryption.
Incomming port should be 993 and outgoing port should be 465 (this ports should automatically appear when choosing an appropriate encryption).
When adding account to Gmail issue can persists even with SSL/TLS (Accept all certificates) encryption. In this case use STARTTLS (Accept all certificates) encryption (port should be 993) for outgoing mail and STARTTLS (Accept all certificates) encryption (port should be 587) for inbound mail.
