I have searched for about an hour now and I find nothing that helps me.
I have cleared all browser data.
I have tried several browsers and multiple PCs.
This started after i upgraded to the latest vCenter update.
I couldn't fix it, so I performed a fresh install of a new vCenter using the latest installer ISO.
All i get is a blue spinning circle regardless of what I do.
Who has seen this?
What does one do about this?
Can u share an image ? Are you able to reach the VAMI page (fqdn:5480) ?
What is the build from VAMI if you are able to login.
Had this same issue. Strangely enough I would get the spinning circle on my laptop as well as any other VM I had access to. This definitely indicated an issue with the vCenter and not with the browsers (IE, Edge, Chrome, Firefox) as I had tried them all. I did clear cache and so on my laptop to no avail. I found an article about the the VMware vSphere Client. I decided take a look and found out that the service was running low in memory or so there was message about it in the vCener Center Management console under services. So I went ahead and restarted the service to clear that message and incidentally the login spinning disappeared and have been able to login since then.
Again this was achieved in te https://(vcenter):5480 - Services - VMware vSphere Client
Hope this helps, this worked for me.
