Applicable to:
- Plesk for Linux
- Plesk for Windows
Symptoms
Plesk installation/update/upgrade fails with the following error message:
CONFIG_TEXT: File downloading products.inf3: Error: Couldn't resolve host 'autoinstall.plesk.com', retry...
Error: Couldn't resolve host 'autoinstall.plesk.com', retry...
CONFIG_TEXT: Syntax error in file /root/parallels/PHP73_17/php73-ubt20.04-x86_64.inf3: Error reading end tag.
CONFIG_TEXT: Error: Failed to read product information from the file : Can't process products.inf3: Failed to download the file http://autoinstall.plesk.com/products.inf3:
Could not resolve host: autoinstall.plesk.com
Cause
The address autoinstall.plesk.com (or autoinstall-win.plesk.com for Windows servers) is not resolvable from a Plesk server due to network issues.
In some cases, this can be a temporary issue.
Resolution
-
Retry to update/upgrade Plesk later.
-
If the procedure still fails, perform the checks below and contact your hosting/ISP provider with the collected information for further troubleshooting.
For Linux
-
Connect to a Plesk server via SSH.
-
Check if autoinstall.plesk.com is accessible using the
pingutility:# ping autoinstall.plesk.com
-
Check if autoinstall.plesk.com can be resolved from a Plesk server:
# nslookup autoinstall.plesk.com
-
Verify that firewall is not blocking the connection.
-
Make sure that name servers are correct in the file
/etc/resolv.conf. If in doubt, use Google Public DNS IP addresses as shown below:# cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4 -
Check that there is no
searchrecord in the file/etc/resolv.conf. If thesearchrecord is present, then it prevents DHCP client from updating the file/etc/resolv.conf(if it is updated automatically). Either comment out thesearchdirective or add the link to the host autoinstall.plesk.com as shown below:# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
search example.com autoinstall.plesk.com
nameserver 192.168.0.1
For Windows Server
-
Connect to the Plesk server via RDP.
-
Start a command prompt and check if autoinstall-win.plesk.com is accessible using the
pingutility:C:\> ping autoinstall-win.plesk.com
-
Check if autoinstall-win.plesk.com can be resolved from the Plesk server:
C:\> nslookup autoinstall-win.plesk.com

I am running Plesk version 11.5.30 Update #55, last updated at Sept 24, 2016. This never auto updated. Do I need to update/upgrade to 17.5.3 for the process update of Paralells Panel to succeed (currently failing to update daily)
Hello John Lloyd
If the error is similar to the error from this article, that's server network settings to check.
Try to upgrade to a more modern Plesk version. In case there will error and the OS hasn't reached it's End-of-life yet, Plesk support could assist with the issue.
Thank you Ivan
Having resolved network issue the problem appears to be that my OS is Windows server 2008 R2 is now out of life. Although I can access in Plesk a link to upgrade 17.5.3, the process warns me that problems can arise if I continue. I don't know if I can upgrade to earlier version, its not offered in Pllek panel.

The recommended approach is to prepare a new server with the newer OS version and perform a migration procedure: https://support.plesk.com/hc/en-us/articles/213912645
To install older Plesk version, you may start Plesk installer via CLI:
plesk-installer.exe --console --all-versions
More information may be found here: https://support.plesk.com/hc/en-us/articles/213961885
Thank you Ivan, I was trying to avoid migrating to a new server but seems I have no potion. Plesk Panel is working fine its just failing to update (a message I get daily).
