ERR_NETWORK_TIMEOUT on Zapier: Network connection timeout. Root cause: The automation platform's outbound HTTP request to the target API did not receive a response within the allowed connection or read timeout window. This can be caused by the target service being temporarily unavailable, network routing issues between the automation platform's servers and the target endpoint, or the target API taking too long to process a complex request.'s outbound HTTP request to the target API did not receive a response within the allowed connection or read timeout window. This can be caused by the target service being temporarily unavailable, network routing issues between the automation platform's servers and the target endpoint, or the target API taking too long to process a complex request.'s outbound HTTP request to the target API did not receive a response within the allowed connection or read timeout window. This can be caused by the target service being temporarily unavailable, network routing issues, or the target endpoint taking too long to process the request. Step 1: Check the target API's status page. Before debugging your Zap, check whether the target service is having an outage. Most major APIs have a public status page (e.g. status.stripe.com, status.hubspot.com). If there is an active incident, the timeout is caused by the external service, not your configuration. Wait for the incident to resolve. Step 2: Test the endpoint directly. Use a tool like Postman or curl to make the same API call manually from your own computer. If it times out there too, the problem is with the target API. If it succeeds, the issue is specific to Zapier's servers reaching the endpoint — possibly a firewall or IP allowlist issue. Step 3: Check for IP allowlist restrictions. Some APIs require you to allowlist the IP addresses of the calling service. Zapier publishes its outbound IP ranges in their documentation. If the target API has an IP allowlist configured, add Zapier's IP ranges to it. This is a common cause of timeouts that look like network issues. Step 4: Reduce the response payload to speed up the request. If the API call is timing out because the response is very large (e.g. fetching thousands of records), add query parameters to limit the response: use pagination (limit=50&offset=0), field filtering (fields=id,name,email), or date range filters to reduce the data returned per request. Step 5: Enable Zapier's automatic retry. In the Zap editor, click on the failing action step and look for the "Error handling" option. Enable automatic retries — Zapier will retry the step up to 3 times with increasing delays before marking the task as failed. This handles transient timeouts without manual intervention.
