After update vSphere Hipervisor on the my server and vSphere Client on my machine and vCenter from version 4.1 to version 5.0 I can not to access with my PC to vCenter Server. Error occured with next message:
---------------------------
Could Not Connect
---------------------------
vSphere Client could not connect to "192.168.69.1".
An unknown connection error occurred. (The request failed because the client could not validate the server's SSL certificate. (The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.))
I think, this error ocurred when I was updated vSpere client to version 5.0 don't delete old version of the client. How is to to win this error??? How is to access on my vCenter Server excluding this error and using SSL connection?
P.S. Version 4.1 displayed dialog window with message about validating SSL certificate. And after there are pressing button "Ignore" worked is normaly.
