Issue Plesk refused to connect

Bogdan1

Regular Pleskian
Hi,

I've just installed Plesk Onyx on Clean VPS(Centos 7)
Installation has been successfully installed. But when I try to connect to admin panel I'm getting "Plesk refused to connect". I tried repair plesk but everything is ok. Apache is running

[root@vps*** ~]# service httpd status

PS: I've also tried 17.8 preview and it works. So I don't understand why stable version refuse to work.
PS2: Is 17.8 preview stable enough to run a website on it?

17.8 is pretty stable as it is. I believe it should be released this month but don't quote me on that.

Have you tried both Plesk ports? 8443 for https, 8880 for http.

Run both the following to confirm; will show that there is something running on that port;

[root@plesk ~]# lsof -i:8443

[root@plesk ~]# lsof -i:8880


OVH typically preinstalls - Can you confirm you installed Plesk manually versus using an OVH template?
 
Yes I tried 8880 but getting the same error.
Yes I installed clean centos 7 and run plesk once-click installer.
Code:
sh <(curl https://autoinstall.plesk.com/one-click-installer || wget -O - https://autoinstall.plesk.com/one-click-installer)

Try to telnet to it from your local machine;

Code:
Marks-MacBook-Pro:~ MarkyMark$ telnet plesk.wired-solutions.net 8443
Trying 107.189.48.141...
Connected to plesk.wired-solutions.net.

telnet: connect to address 54.**.**.***: Connection refused

Check the OVH Firewall, that has to be it.

You do get bonus points for using a Mac :D

Looks like there is nothing in OVH's firewall. I can only create.
As I said for some reason plesk preview working just fine except it's always(every click) logging out .

Damn, which repair options have you tried? plesk repair installation?
 
This one:

  • plesk repair all -y - Checks the Plesk installation and all Plesk services. The utility will run in the repair mode (the utility attempts to resolve any issues it detects).
 
Alright, one more attempt, try flushing iptables;

[root@plesk ~]# iptables -F
