Labs is not accessible



I am trying to access lab console form and console is not opening. I can see below message: refused to connect.

Please help in accessing the lab. Thanks.


I am able to log in just now. Since the upgrade is in progress you might see some interruptions. Request you to try again.

Please paste the screenshot and labs user name to troubleshoot if you are facing the problem.



Thanks for your quick response.
I am able to access the lab now. Thanks.
