Resolved Roundcube ERROR: Connection has been rejected (111)

[Dennis de Jong]

Dear Plesk,

When a customer of us try to change his password in Roundcube it gives him or her the following error:

Translated text:

An error has occurred!
New password cannot be saved;
connection error;

The log of Rouncube gives me the following error when I try to change the password in Roundcube:

ERROR: Connection has been rejected (111)

I don't know what goes wrong and what I need to do to fix this problem, on other Plesk versions of our servers the password change works. But on this one it won't work.

When I try to Google on it, I can't find much about it, the only thing I found is some kinda bug in Plesk. But I don't know if it has something to do with my error.

Please let me know!

Cheers,
Dennis

Hi Dennis de Jong,

I have the feeling, that you hit a current bug:

=> Unable to change password in Roundcube​

Could you pls. check with the provided steps to reproduce from the KB - article?

 

[Dennis de Jong]

Dear UFHH01,

I followed the KB - article with the following results:

[root@ds01 ~]# /usr/local/psa/admin/sbin/poppassd
200 poppassd hello, who are you?
[email protected]
500 Username required.

[email protected] > stands for a customer email and domain like [email protected]. I tried some customers in the example but it still give me the "Username required".

Does this mean the username of the Plesk user or something else?

Cheers,
Dennis

Hi Dennis de Jong,

actually, I just tested the "Password - change" options for Roundcube on several servers and couldn't reproduce your described issues there.
Could you pls. add your current used operating system and the current used Plesk version ( incl. #MU ) ?

Afterwards, could you pls. confirm, that you don't use additional Roundcube plugins, which might interfere with the built-in ability to change passwords over "poppassd" ?

Dear UFHH01,

OS: CentOS Linux 7.4.1708
Plesk: 17.5.3 Update #22

I did change some template in the past, but it was overided when the next Roundcube update was added.
I also tried to change template in Roundcube but that does'nt change anything.

I know for sure I did not change anything in the core of the "poppassd". But is there a way to see what goes wrong?

I have a simular error message from the log that I can't explain where it is comming from:

<7b04lvm0> PHP Error: SieveRules plugin: Unable to open file /etc/dovecot/sieve/default in /usr/share/psa-roundcube/plugins/sieverules/sieverules.php on line 2874 (GET /roundcube/?_task=settings&_action=plugin.sieverules.add&_framed=1)

Is there a way to delete Roundcube and do a fresh install? If you delete it from the "Updates and Upgrades" it won't remove everything.

Please let me know!

Cheers,
Dennis

Hi Dennis de Jong,

hm... I can see, that you recently upgraded to CentOS 7.4, even that it isn't supported by Plesk yet. ( Pls. see: => Question - Plesk Onyx & CentOS 7.4 compatible? ). At the moment, Plesk developpers are investigating and testing the possible upgrade, but the expected announcement ( with possible updates/upgrades/patches for Plesk ) is to be expected for September 25 ( => #2 ).

 

[Dennis de Jong]

Dear UFHH01,

Then I have enough information and we will work with a workaround "change a password using Plesk web interface.".
Let's hope it wil be fixed on the 25th of september.

Thanks for the information and have a nice day!

Cheers,
Dennis

Dear Plesk,

I have updated to the new version of Plesk.

17.5.3 Update #23

I still got the error that I can not update my password in the Roundcube webmail.

You have any idea what to do next?

Cheers,
Dennis

Note that password changing is performed by poppassd service which should be running and listening on port 106:

# lsof -i | grep poppassd
xinetd 4662 root 7u IPv6 1569054342 0t0 TCP *oppassd (LISTEN)

# lsof -i tcp:106
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
xinetd 4662 root 7u IPv6 1569054342 0t0 TCP *oppassd (LISTEN)

 

[Dennis de Jong]

Dear IgorG,

The above commands give me no results, I think there is someting with my poppassd.
How can I troubleshoot this and restore this?

Cheers,
Dennis

 

[IgorG]

First of all check that you have this file:

# cat /etc/xinetd.d/poppassd_psa
#ATTENTION!
#
#DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
#SO ALL YOUR CHANGES WILL BE LOST AFTER YOU UPGRADE PARALLELS PLESK PANEL.
service poppassd
{
socket_type = stream
protocol = tcp
port = 106
wait = no
disable = no
user = root
instances = 1000
flags = KEEPALIVE IPv6
server = /usr/local/psa/admin/sbin/poppassd
}

After that check that xinetd service is up and running:

# systemctl status xinetd
● xinetd.service - Xinetd A Powerful Replacement For Inetd

Dear IgorG,

The file "/etc/xinetd.d/poppassd_psa" is missing but the service is running, can I use the above file settings to restore it?

[root@ds01 ~]# cat /etc/xinetd.d/poppassd_psa

[IgorG]

can I use the above file settings to restore it?

Yes, try to create this file with this content and restart xinetd after that. Check that poppassd service is up and running.

Dear IgorG,

That did it! It works like a charm now, thank you very much!

Dennis
