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...
OR
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
ping
utility:# 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
search
record in the file/etc/resolv.conf
. If thesearch
record is present, then it prevents DHCP client from updating the file/etc/resolv.conf
(if it is updated automatically). Either comment out thesearch
directive 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
ping
utility: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
