Clients sees local flyweel live website weird

Hello,

I created my first website whit flywheel local.
I now want to show it to my client whit the live link.
But when they see it the website looks white whit only text. No images or colors appear.
When i click on the live link i see the website as i made it.

What can be wrong?

Thanks Remco
