I've found no fix but at least a quick way to force the switch between servers. On the dashboard, if you go to server details for the server you wanna see, then click on the refresh button a couple times then click on server management, it should switch to the server you want to look at.
The Unraid Connect webgui is not allowing me to switch between my three servers. It will connect to the first one I select then not switch to the other two when selecting server management for that machine. I'm not sure how to fix this issue.
