Unable to Login to vCenter

[tigerhawkz]

I am currently unable to login to my vCenter 6.5 web client. I keep getting an error "User name and password are required" when trying to login. I only get the error when imputing a correct username and password. I have used multiple user accounts and computers with the same error. Anyone have any idea on how to fix this?

if u are installed vcenter for the first time try:

login: [e-mail]

password: ( the password that u configured in setup process)

Thanks for the reply. I've tried the [e-mail] account and get the same error.

I have entered the same credentials for the ESXI and it worked with me. 

In my case the username is root and password that you've assigned.

are you using vsphere web client flash?
Have you tried using html5 client? https://vcenter-fqdn:5480

let me know  how that works

I was going to https://vcenter-fqdn/ui/ when I got the error. I just tried going to https://vcenter-fqdn:5480/ and logging in but get "Unable to authenticate. Try again."

Sorry, my mistake, you wont be able to log un to :5840 with [e-mail].

You might with root, but it's not vsphere client

Have you tried using other browser?

[tigerhawkz]

Yes I have and on another computer.

[SOLVED] vCenter login failing - Spiceworks

I have some additional information. When trying the IP of vcenter I get the following error:

[400] An error occurred while sending an authentication request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - com.vmware.vim.vmomi.client.exception.ConnectionException: java.net.SocketTimeoutException: Read timed out.

Looks like sts certs are expired..

That's what I was thinking. I figured out that I needed to Regenerate a new VMCA Root Certificate and replace all certificates.
