Hi,
While checking your website, I didn’t spot any issues with these events.
The event is present in the data layer, and when checking the network, the request is being sent to the server container.
To debug the causes, I would advise you to run a preview of the web and server container and check the outgoing requests from the server to the relevant platforms. This will help determine whether there are errors specifically in the outgoing requests.
I also recommend that you enable logging of outgoing requests in your container on Stape. This will allow you to check your logs for errors in the outgoing requests.
