Hosted domain connection refused - help...

[elcopdoo]

We have latest Plesk 12 on Centos 7,
I can login to Plesk UI and mail is working,

but cannot access hosted website www.elcop.hr :
Error: Connection refused

Anyone can help?

Make sure that port 80 is not firewalled there. I have checked accessibility of this port and I see:

# telnet elcop.hr 80
Trying 92.242.243.163...
telnet: connect to address 92.242.243.163: Connection refused

 

[elcopdoo]

I disabled firewalld and selinux, what can I do next?

I disabled firewalld and selinux, what can I do next?

Is this correct IP address for this domain - 92.242.243.163 ?
Have you checked Apache logs? Can you connect to port 80 of this domain directly on this Plesk server?

 

[elcopdoo]

IP is correct,
[root@server2 ~]# telnet elcop.hr 80
Trying 92.242.243.163...
telnet: connect to address 92.242.243.163: Connection refused

Seems that port 80 is blocked but with what?

I tried to disable failban and Plesk firewall with no luck...

 

[IgorG]

What about output of command

# lsof -i tcp:80

on this Plesk server. Are you sure that Apache is up and running?

 

[elcopdoo]

No output on lsof -i tcp:80,
according to Plesk Apache is running...

 

[IgorG]

Check that Apache is really started:

# /etc/init.d/httpd status
httpd (pid 26544) is running...

 

[elcopdoo]

[root@server2 ~]# sudo systemctl enable httpd.service
[root@server2 ~]# sudo systemctl start httpd.service
[root@server2 ~]# lsof -i tcp:80
[root@server2 ~]# systemctl is-active httpd.service
active
[root@server2 ~]# sudo systemctl restart httpd.service

After reboot issue remains...

 

[elcopdoo]

I decided to reinstall Centos 7,

could You explain how to open needed ports for Plesk in Centos 7?

I decided to reinstall Centos 7,

could You explain how to open needed ports for Plesk in Centos 7?

All necessary ports for Plesk listed in this KB article http://kb.odin.com/391

 

[elcopdoo]

I know which ports, I need procedure for opening ports in Centos 7 minimal...

I tried with:
SELINUX=disabled
and
firewall-cmd --zone=dmz --add-port=xx/tcp --permanent
firewall-cmd --reload

I cannot login to Plesk...

If I turn off firewalld completely, does Plesk replace with it's own firewall?

 

[elcopdoo]

I finally resolve ports issue with
firewall-cmd --zone=public --add-port=xx/tcp --permanent

 

[elcopdoo]

Unfortunately, problem reappeared after few hours:

Connection refused

This time opening ports is not helping:
# firewall-cmd --zone=public --add-port=80/tcp --permanent
# firewall-cmd --reload

I can login to Plesk GUI and mail works, but domain site and webmail not (Connection refused).
I completely reinstalled Centos 7 and Plesk and all worked till now...

Is this a problem in Plesk?
I noticed that after fresh installation Plesk dont give option to update to last MU 13.

 

[elcopdoo]

Update:

1. Restarted NGINX
2. Restarted APACHE

Access to website now works..

Seems that NGINX and/or APACHE get stuck at some point...

Still no way to update to MU 13...

[elcopdoo]

After few more hours NGINX get stuck again,
I get 504 Timeout error.

Please give instructions how to find the root of this instability...

 

[elcopdoo]

What is this:
PHP Fatal error: Uncaught exception 'Service_Driver_Exception' with message
'Cannot reload proxy server: ' in /usr/local/psa/admin/plib/Service/Driver/Web/Proxy/Nginx.php:116

Update:
hapened twice today
after server restart domain is not accessible until I restart NGINX and APACHE..

 

[OussamaD]

NGINX restart solved the problem

I had the same problem as above. After i restarted the NGINX module website was online again. One obvious thing that i mentioned is that not all of the webpages were offline.

Strange error but solved

 

[domenik]

I have the same issue!

Fresh CentOS 7 install and newest plesk 12.

When I reboot the server, ports 80, 433 not responsive! I need to restart nginx module or disabled it! This is cleary a Plesk Bug and should be resolved ASAP!
