Unable to connect

Hello, I am currently unable to connect to the practice tests for Certified Kubernetes Administrator. Have tried multiple different tests, and I get stuck on this screen

Hello, @jpatricknola
It’s working now.

Thanks for the quick fix!

Labs down again, with the same error message / behavior
But this time it is the CKAD labs

Any ETA for when it’d be resolved?

from the slack channel:

The slow loading of the labs is currently due to the quay registry outage.
As a result, the flannel CNI is not deploying which is needed for most of the labs to be initialized.
You can check the status here - https://status.quay.io/

looks like a different problem. Rough week for the k8s labs

Hello, @ocfernandes1
You can access now, It’s working fine.

For me labs are also down, I cannot access any. @player001

@arfallas, Can you please go through the troubleshooting steps?

I went through all the troubleshooting steps and I am still getting the same behavior, labs are stuck on connecting.

It will stay like that until the lab timeout I can see the background terminal being updated though. @tgp

Can you please provide us with the console logs. Also, did you try using incognito mode?

Here are the logs @tgp

@arfallas, is there any javascript blocker in the browser?
