  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,, 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).

See the following link for more details on TCP window scaling

If the issue still persists, open the /etc/hosts file and replace:
