Observability engineer training

I have a problem with the training. In the lab instructions, there is a link to open kibana and practice the lab but when I click on it, it opens a page that tells that can't reach this page.
I tried to use different browsers but still, the problem didn't solve.

What should I do I can't complete my training while I can't go to kibana and practice.


I have tried the suggestions in that page but still the problem didn't solve

Good day! Apologies for the delay in our reply here. My first thought is that the kibana server itself was not running for some reason. If your session is still available, I can try to log in and investigate.
