I am the support technician for the IT faculty at a college.
We have a small vSphere lab environment with a single host running ESXi 5.1. We use this for students to practice networking tasks on isolated networks without the need for lots of physical hardware.
I have recently upgraded our VCSA to 5.5 for the support for more virtual machines with the embedded database. I have also upgraded the vSphere Client and Intergration Plugin to 5.5.
Before the upgrade, in order for a student to access a virtual machine on the host we would provide the virtual machine's web client URL, on opening this URL the student would be presented with the web client logon page and once logged in the VMs desktop.
Since the upgrade, upon opening the URL I get a message: "The page at https://VCSA_IP_Address:9443 says: null". I click OK, the message clears but nothing further happens with the page, no logon screen or desktop.
If I log onto the web client first (https://VCSA_IP_Address:9443/vsphere-client/#) I can then launch consoles or open other saved URLs normally.
Any ideas as to what has gone wrong? Is there something I haven't done or is 5.5 different to 5.1 in this respect?
Any help will be gratefully received.
