I run into the same problem today (Windows 10 Firefox 104.0.2 and Edge 105.0.1343.42) in the lab of DO180-4.10. No Openshift details are displayed. I opened a ticket and now I'm waiting for a response ... let's see how long it takes.
--> So it seems the issue is not really solved. It still occurs from time to time.
Edit: Support could fix it within 3h by "recreating my lab environment". Thanks!
I just tested DO180 4.10 on RHU (Red Hat associates) and ROL (customers). The first time I created a ROL lab, I did not get the connection details displayed, but in RHU it worked well on the first attempt, and retrying on ROL (by deleting and creating the lab again), gave me the connection details.
If any of you has already retried and you cannot get the connection details no matter what, then I'd suggest you open a support ticket- although there might be a problem affecting multiple users, I think it's best if you get individual support to troubleshoot your specific case.
