Problem after upgrade to vCenter 6.5

Hello,

Yesterday I upgrade successfuly my vCenter 6.0 to 6.5 and since then I am not able to log in into my vCenter via vSphere client.

Error message is:

An internal error occurred in the vSphere Client.

Details: Object reference not set to an instance of an object

My ESXi hosts are version 6.0 and vCenter 6.5.

I tried to re-install vSphere client and removing vCenter and installing again, did not help.

Does anyone know how to fix this issue?

Thank you!

Welcome to the Community,

vSphere 6.5 doesn't support the Windows based C# Client anymore. You'll have to use the Web Client.

see e.g. https://kb.vmware.com/kb/2147929
