Server side tagging issues
I’m migrating client side GTM Tags to server side. Tagging server is deployed in k8s (not cloudrun). The container config is in a secret and we checked all urls are completed routed. Staging URLs are working OK but prod urls are failing.
• track.mysite.com is receiving requests and returning 200s.
• Event delivery is inconsistent — yesterday one event made it to our Add Partner Dashboard but wasn’t logged in Datadog, and another did the opposite.
I need the preview panel working to debug this — it’s the only way to inspect event payloads and validate that the right events are reaching the right partners without affecting production data. Right now I’m flying blind on two fronts:
• When using preview-track.mysite.com as the GTM debug URL, the page loads without errors but the preview panel shows “No tags were evaluated in this container” — no events are captured.
• When switching to track.mysite.com as the debug URL instead, I get a security challenge: “One more step… The security system for this website has been triggered”, followed by “Unable to connect to the website — this error may be caused by a problem with preview-track.mysite.com, which is preventing the security verification process from completing”.
Not sure where to start looking. /healthy for preview server and preview container are returning OK
