If you load this image in your web browser, (In this case using this web address: https://mautic.mywebsite.com/email/632dc6c71bc8e110411075.gif) a 1x1 pixel size tracking image should appear. Unless you have pixel sharp vision, you won’t see it, but if you don’t get an error, then it’s there, so all working good.
No, specifically I mean that when I insert a focus windows in any page, I receive the error 404 regarding the resource https://my_mautic.com/focus/2/viewpixel.gif.
I checked another previous installation of mautic and I can access the indicated resource.
In my server logs I do not find any related error.
The email tracking pixel is working perfectly. Only happens with focus windows
