'unknown CA' after domain problems had been fixed (by my hoster)


#1

Domain: acegames.de
OS: Debain8 on Linux Vserver
Hoster: Kramer Betriebs GmbH
Web-Server: apache2
ControlPanel: no
SSH: Yes
Working Mailserver: yes ( Postfix+dovecot)
How: Using Ajax Request in php to make file mail_send.php send an email via swiftmailer with tls encryption

SysLog:

SL3 alert read:fatal:unknown CA
SSL_accept:failed in unknown state
SSL_accept error from 553182-561.pph-server.de[137.74.140.78]: 0
warning: TLS library problem: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1300:SSL alert number 48:
lost connection after STARTTLS from 553182-561.pph-server.de[137.74.140.78]
disconnect from 553182-561.pph-server.de[137.74.140.78]

problem remains after deleting certificate and related files, recreating

mail_send.php?err=ERRORMESSAGE&time=00-00&user= UNKNOWN:

require_once ‘swiftmailer/lib/swift_required.php’;

$error = $_GET[‘err’];
$time = $_GET[‘time’];
$user = $_GET[‘user’];

// Create the mail transport configuration
$transport = Swift_SmtpTransport::newInstance(‘acegames.de’, 587, ‘tls’);
$transport->setUsername("***@acegames.de");
$transport->setPassword("***");

$mailer = Swift_Mailer::newInstance($transport);

$message = Swift_Message::newInstance(‘Teamspeak Error Report’);
$message->setFrom(array(‘admin@acegames.de’ => ‘Admin’));
$message->setTo(array(‘report@acegames.de’ => ‘ts3 report’));
$message->setBody(
’’ .
’ ’ .
’ ’ .

Reported Error: ’ . $error . ‘

’ .

Time: ’ . $time . ‘

’ .

User: ’ . $user . ‘

’ .
’ ’ .
’’,
‘text/html’
);
// Send the email
$mailer->send($message);

In my Webbrowser’s (Chrome) console i get this:

GET https://ts.acegames.de/mail_send.php?err=undefined&time=undefined&user=undefined 500 (Internal Server Error)

it’s not interesting thet undefined means that there is no value. The fact that it’s outputting a 500-Internal-Server-Error is interesting by i dont get where the problem is.


#2

btw. i could not connect to my webserver either (it took about a day. then everything looked fine again)
because of the same cert error as in the syslog.
But no 500 error.
Seems like the file caused the 500-error because of the certificate error.


#3

This looks like a misconfiguration in your mail server. This isn’t an apache error ( the cert is correct there), rather a mail error.

When I test I get;

Unable to open a socket to 137.74.140.78:587. Fatal error: Can’t connect to “137.74.140.78:587”

Is there a firewall on your server blocking access to port 587 ? and is postfix running on your server ? any errors in the log for the mail server ?

ive just asked my hoster if there is any firewall blocking the port. waiting for an answer…zb


#5

ive just realised that im not using STARTTLS so port is 465 but now i get ERR_CONNECTION_REFUSED on my whole apache2 server (acegames.de and its subdomains)

apache crashed. it had already crashed yesterday at 9:39 PM. but i was unable to find the error messages yesterday. so apache crashed because it could not find the certificate defined in the vhost files.researching…


#6

i cannot find any error, relating to the 500-INTERNAL_SERVER_ERROR…

btw apache is now running with perfectly fine cert settings.


#7

OK, now you have fixed those things, I can also connect correctly to port 587.

Are you still getting the 500 error ?


#8

yes… it is still a 500-INTERNAL_SERVER_ERROR if, open up the site:
https://ts.acegames.de/mail_send.php?err=error&time=00-00&user=username


#9

What is there in your apache log ? (and error log)
