What does this error means when trying to connect smtp (mailersend.com)?
- Failed to authenticate on SMTP server with username "MS_uY4Nyi@licente24.live" using the following authenticators: "LOGIN", "PLAIN". Authenticator "LOGIN" returned "Expected response code "235" but got code "535", with message "535 Authentication failed.".". Authenticator "PLAIN" returned "Expected response code "235" but got code "535", with message "535 Authentication failed.".".
