403-Forbidden when opening labs from CKAD-Labs

Hi,
I get 403-Forbidden when I try to access https://kodekloud.com/courses/labs-certified-kubernetes-application-developer/
It has already worked for me - I managed to do some labs. But it does not work anymore.
What can I do with it?
I’ve tried Chrome and Safari browsers.

Can you please try now? @Lukasz2021

it works fine now, thank You!
