GA4 lead event discrepancy

Hello, everyone.
I have configured 2 different GA4 properties: 1 server, 1 web.

I would like to understand why my GA4 server side property receives fewer events than the GA4 web property.

In detail, the events where there is a discrepancy are shown below


As you can see there is a lot of discrepancy: GA4 web has many more lead events than GA4 server.

How can we fix this?
What information can I provide you to understand what’s happening??


The first thing to do is to check in debug mode GA4 if all events are coming through the server. Most likely the problem is somewhere in the configuration, or maybe the problem is with the consent status, if you have one.
