Cause
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.
Resolution
Warning: Consider this solution as temporary. Revert the changes as the CDN server will up and operable.
Use another replica of the Plesk repository until the local CDN server synchronizes with it. To do this perform the following:
- Visit any 3rd-party DNS checker (for example https://dnschecker.org/#A/autoinstall.plesk.com) to determine the IP address of the nearest available host to the Plesk server.
- Connect to the server via SSH
- Configure a static resolution rule in the file
/etc/hosts. Open this file for editing - Insert IP address from step #1 to forcefully resolve Plesk installer to another replica, for example:
CONFIG_TEXT: 185.93.1.5 autoinstall.plesk.com
If this does not help, contact the network administrator to check why the server cannot reach autoinstall.plesk.com.
