Set up a on your server so that the data center firewall only sees encrypted traffic going to the VPN IP, not the restricted DL3/DL4 IP. Step 3: Use a Residential Static IP
This article breaks down the technical reasons behind the restriction, the hidden risks of trying to bypass it, and the best practices (the "better" approach) for efficient, legal downloading in restricted data center environments.
: Identify the specific IP addresses associated with the dl3 and dl4 subdomains and add them to the explicit allowlist in your hardware firewall (e.g., Cisco ASA, pfSense, or Fortinet). Set up a on your server so that
Configure your download client or application to use a premium or an HTTP proxy .
Our data center has flagged DL3 and DL4 as high-traffic nodes that were beginning to degrade performance for the wider network. To prevent a total system slowdown, they have applied "throttling" or access restrictions to these specific nodes. Configure your download client or application to use

Due to these restrictions, users attempting to connect to these specific endpoints will experience connectivity issues or failed downloads. This change affects all traffic routed through our primary data center infrastructure attempting to reach these destinations. Have you encountered this restriction on a specific
The specific combination “DL3 and DL4” suggests that these two servers belong to the same logical group—perhaps both are designated for free users, or both are located in a particular data center with strict usage policies.
Instead of hard-restricting DL3/DL4, return a Retry-After header with a 429 status code. This tells the client to wait a few seconds or minutes, reducing frustration compared to a cryptic “restricted” message.
