[hale177]

problem

I just new install v4.20.1 these two days, two nodes and one mgmt (vm instance), everything be ok, but when I got to the UI wizard zone, after all the settings were completed and I clicked Launch, the UI always stuck at creating zone and didn't respond.

UI No error reported, always stuck at creating zone，Chrome F12 also shows that the same request URL is being printed all the time

@kiranchavala

I have uninstalled 4.20.1 and plan to downgrade to new install 4.20.0, wait for my test results

But can you upgrade your oracle linux 8.6 to the latest OL-8.10, like execute dnf upgrade -y and reboot os, after see UI wizard zone it still works ？

I've been pretty busy lately, but just wanted to give an update: As mentioned above, after switching to Rocky 9.6, everything is working perfectly now. So awesome!
