Error when trying to create a new reservation for the virtual lab

[linux-sas-admin]

I am getting the following error when attempting to make a new reservation with the virtual lab. The issue started on 02/08/2024.  I have sent an email to elearn@sas.com but not response as yet on the issue. 

"Reservation not made successfully. Error message received when creating reservation:

Server Error

502 - Web server received an invalid response while acting as a gateway or proxy server. There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server."

Hi:
It was my understanding that there was some kind of server/firewall change that impacted the Virtual Labs for some, but not all of our classes. Our server support team is working on identifying and fixing the issue. Around noon, I believe that they made all the corrections, but now they need to wait for the updates to propagate to all the individual servers.
We do apologize for the inconvenience. Please try your reservation again later this afternoon.
