Hi,there could be the below reasons for your error.
-Verify the email server settings: Confirm that the email server settings (SMTP/IMAP/POP3) are correct. The server address, port number, and encryption method (SSL/TLS) should be accurate.
-Account-specific issues: Ensure that the email account you are using for authentication is active and has not been locked or suspended due to any suspicious activity. Sometimes email security issues.
