Cause

  1. Plesk uses a content delivery network (CDN) to distribute Plesk packages. This technology uses several cache servers which are distributed across different parts of the internet. All of the servers share a common domain name, autoinstall.plesk.com, which resolves to different IP addresses depending on the network segment that a request comes from. Sometimes, a server becomes out of sync with the main replica and files go missing.

  2. Network issues (TCP window scaling).

Resolution

Use the main replica of the Plesk repository until your local CDN server synchronizes with it. To do this, configure a static resolution rule in the file /etc/hosts:

87.245.204.21 installer.plesk.com

If this does not help, disable TCP window scaling:

echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
