**Your software**  
My Mautic version is: 3.3.3  
My PHP version is: 7.4

**Your problem**  
My problem is:  
I can see that Mautic is tracking anonymous users, however it is not merging them with contacts.

I am sure I have seen this issue before but could not find it.

My setting in WP-Mautic

Is there a way to debug this or fix it ?

These errors are showing in the log:

Hey @joeyk

Yip, all SSL is good. Nothing coming up in error logs or console.

Mautic is sitting on a different domain from site being tracked. So site is [https://displaysite.com](https://displaysite.com) and mautic is on [https://companyname.com](https://companyname.com)

I have however had the same setup even with Mautic tracking multiple sites and not seen this issue

> Can I ask to clarification on this—in the example are you using [mautic.domain1.com](http://mautic.domain1.com) and [trackingdomain1.domain1.com](http://trackingdomain1.domain1.com) interchangeably? Or are you suggesting to somehow create a second subdomain on domain1 to dedicate as a tracking domain? My understanding is that, in addition to the standard setup, if I want to use the primary mautic instance to track a secondary domain, I should go into DNS on domain1 and create a CNAME that points from the [mautic.domain1.com](http://mautic.domain1.com) subdomain to [domain2.com](http://domain2.com).
