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
Server:

Web:

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??

Thanks!

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.

@giovanni_fabbrocino did you end up getting to the bottom of this? I have a server side and client side property running in parallel and am seeing a fairly large discrepancy in lead form conversions as well.

I can see the event is being sent to the server container and is appearing in the GA4 debug view during testing, but I haven’t been able to determine a cause for why this might be.

Using two web and server properties in parallel is bad practice, it will never work correctly. It also doesn’t make any sense.
The server container in case of GA4 acts just as a proxy, it redirects traffic further to GA without any changes to it.

Hi Guys,

sorry for the delay;

the answer to @steven_konstruct is: yes I fixed!

the problem was related to consent mode and data modeling;

now with consent mode V2 we’re not facing any of this problems on events;

however we’re facing other problems related to channels in GA4, but this is related to Consent mode V2;
