GTM SS: No Client Claimed the Request - Troubleshooting Guide
Blog post from Snowplow
Implementing server-side tagging in Google Tag Manager with Snowplow can enhance event tracking, but users may encounter the "No Client Claimed the Request" error when configuration issues arise. This error typically occurs when the Snowplow client does not recognize the request path, often due to discrepancies between the expected and actual POST request paths. To resolve this, users should verify that the POST request targets the correct path, update the client configuration if needed, and ensure that GET requests to /i endpoints work properly to isolate the issue. Additionally, checking for 404 errors and confirming that the GTM SS container is correctly deployed can help address these problems. By addressing request path mismatches and deployment misconfigurations, users can effectively mitigate the error and improve their server-side tagging setup.
