Preconnect Not Showing?

[Davwaii]

Hi Guys,

Can anyone please explain why the preconnect isn't showing on Google Analytics?

Normally it shows the three colored bars for DNS - Connect - SSL.

When I preconnect, you usually see the bars move to the left slightly, but on certain domains recently they seem to have disappeared, as is the case with this one.



Any help is welcome and appreciated.

Thanks.
