Update and Upgrade Link not working

[Sally1]

Hello,

I had to reinstall fresh my web-server. I have now installed

OS ‪CentOS 6.10 (Final)‬

Product Plesk Onyx
Version 17.5.3 Update #52, last updated on July 5, 2018 09:27 AM

But now I have the Problem, that the Link under Tools & Settings - Updates and Upgrades is not working. I tried with different browsers, but get just cant open page, can't establish a secure connection.

I tried this to fix it:

ps auxxf | grep install

Killed the running installer process. and tried again, still the Link is not working.

Reboot of the server is also done.

Any Idea what else I can do to get the Link working?

Thx
Sally

Hello Sally does the Plesk installer over SSH work?

Make sure that port 8447 is not firewalled.

Hello Arashi, yes the plesk installer seems to work I upgraded from plesk 12 to 17.5.3 via command line. But I dont know, how I can add via command line the components what I urgent need to do after the website recovery ..

Hello IgorG,

when I check netstat -natp | grep :8447 I get yet

# netstat -natp | grep :8447
tcp 0 0 :::8447 :::* LISTEN 1953/parallels_inst

 

[IgorG]

when I check netstat -natp | grep :8447 I get no result ...

You will see output here only when you click "Updates and Upgrades" link in Tools&Settings

 

[Sally1]

ok, output is yet tcp 0 0 :::8447 :::* LISTEN 1953/parallels_inst

 

[IgorG]

But can you connect to this port from your workstation where your browser opens Plesk Installer page?

 

[Sally1]

no, seems the port is closed to 8447

 

[IgorG]

no, seems the port is closed to 8447

So, as I wrote above, check your firewall settings.

 

[Sally1]

I have Plesk console the firewall not installed yet, why is the port then blocked? Why is port 8443 open, and works?

how can I enable the port via command line?

Thx

When checking ip tables get this result

# iptables -nL | grep 8447
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:8447
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:8447


Means the Port is open and connection should be allowed. but when doing telnet to the port its not open, and when clicking the updates & upgrades Link I get the message failed to open page ...

 

[Sally1]

checking with nmap get the following result:

PORT STATE SERVICE
8447/tcp open unknown

 

[Sally1]

When checking Port 8443 I get the following result

PORT STATE SERVICE
8443/tcp open https-alt


I have done this yet:

iptables -I INPUT -p tcp -m multiport --dports 8443,8447 -j ACCEPT

But still cannot not open https://82.x.x.x:8443/admin/update/product/ Link ....

Any Idea what else I can try?
