javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

  • Hi!

    My question is about setting up email in Rollbase Private Cloud. (my laptop with Win 7 Ent).

    I configured the Email Server: Administration Setup -> Email Server Settings.

    Test Settings is Ok. I received a email on the test email address.

    But, when I created new user (or reset password for him) this user not received email about this. In the log file I see this error message from Java:

    [2013-11-28 11:29:54,737] Password for user Test User has been reset by Valeriy Admin at 11/28/2013 11:29 AM
    [2013-11-28 11:29:54,737] Passwords for 1 users have been reset.
    [2013-11-28 11:29:54,827] ===> Error in thread MailQueue at 11/28/2013 11:29 AM
    [2013-11-28 11:29:54,827] javax.mail.MessagingException: Exception reading response;
    nested exception is:

    Maybe someone knows what I need to do to fix it?

  • Is the flag "Use SSL to connect to mail server" in Email Settings checked or unchecked ?

  • Are u using an SMTP Proxy ?

  • This flag is checked. "Test Settings" working good.

  • >>Are u using an SMTP Proxy ?

    Yes

  • Can you share some details of the SMTP Proxy Server Software ? We use JavaMail API and it does not support HTTP Proxy Servers for SMTP..

  • Hmm, I do not understand what happened, but when I reinstalled rollbase through ROLLBASE_FULL_INSTALLER_2.0.0.4_WIN_64.exe, rather than manually as before - it work now. Only now uses Java which established the installer. The previous version of Java and the current version of Java are the same.

    I think it depends on the settings of Java. Just do not understand what settings were needed.
