Web plesk panel : ERR_CONNECTION_REFUSED

[Jonathan Michelon]

Hi all,

I have parallels plesk autoinstaller on my server and since the new microupdate during that night i haven't access to my web panel.

/etc/init.d/psa status is running
/sbin.iptables -L are accept
lsof - i tcp:8443 -> Listen for root and sw-cp-server

I don't know what happened !
May you have a solution ?

Thanks
Jo

Can you connect with disabled iptables?

 

[Jonathan Michelon]

How can i try that ?

 

[IgorG]

Just switch off iptables in command line and try connect to Plesk Panel.

 

[Jonathan Michelon]

Still not working

Any ideas ?

 

[Oliver Meyer]

Which distribution do you use?

 

[Jonathan Michelon]

Centos

 

[Oliver Meyer]

Have a look if iptables is still running

systemctl status iptables

If it is running, you can stop it via..

systemctl stop iptables

Then try to connect to your Plesk-Panel

If it does not work, have a look if firewalld is running:

systemctl status firewalld

If yes, disable it via:

systemctl stop firewalld
systemctl status firewalld

Then try to connect to your Plesk-Panel

Hi Oliver,

Thanks for your answer.

The comand you gave to me are not working.
But this is what i just did :

# /etc/init.d/iptables stop
# chkconfig iptables off

# service ip6tables stop
# chkconfig ip6tables off

but it still not working

Sorry, thought you are on CentOS 7.

Anything in your plesk-logs?

/usr/local/psa/var/psasem.sem file is empty

 

[Oliver Meyer]

Maybe your last update went wrong - you could
try to reinstall the microupdates.

/usr/local/psa/admin/sbin/autoinstaller --select-release-current --reinstall-patch --install-component base

If that does not help, you could try to let plesk generate new semaphore files:

service psa stop
cd /usr/local/psa/var
mv utilities.sem utilities.sem.bak
mv psasem.sem psasem.sem.bak
service psa start

 

[Jonathan Michelon]

thank you for your time...

So,
Nothing changed after reinstall ...
Nothing with semaphor bak files

 

[Oliver Meyer]

As last resort, try to repair your installation:

/usr/local/psa/bootstrapper/pp12.0.18-bootstrapper/bootstrapper.sh repair

If that doesn't help, you should think about a support-ticket.

 

[Jonathan Michelon]

Thank you for your help Oliver.

Nothing happened even with the reparation.
I'll open a support ticket !

Thanks

 

[Jonathan Michelon]

The problem is solved !

The issue was caused by misconfiguration. In /etc/sw-cp-server/conf.d/plesk.conf ssl port was set to 2015:

*****
server listen 2015 ssl;
Set port to default 8443 and restarted sw-cp-server
*****

Thanks to the support team !
