Custom connection and read timeouts control how long Gcore edge nodes wait when communicating with an origin server.
  • A custom connection timeout sets the maximum duration allowed for establishing a connection.
  • A custom read timeout sets the maximum duration for receiving a response from the origin server. This timeout applies between two successive read operations, not to the entire response transmission.
When designated timeouts are exceeded, users receive a “504 Gateway Timeout” error.

Configure custom timeouts

Timeouts are configured per CDN resource and apply to all requests handled by that resource. 1. In the Gcore Customer Portal, navigate to CDN > CDN resources.
CDN resources list page
2. Click the CNAME of the required CDN resource to open Resource settings.

3. Click Custom connection timeout or Custom read timeout, depending on the timeout to configure. 4. Enable the Customize connection timeout or Customize read timeout toggle. 5. Enter the timeout value. The allowed range is 1–5 seconds for connection timeout and 1–30 seconds for read timeout. To configure both timeouts, repeat steps 3–4 for the other option before saving.
For Enterprise plans, the upper limits can be raised beyond 5 seconds (connection) and 30 seconds (read). Contact Gcore Support to request higher values.
