vCenter 4.0 Logon fails: Server could not interpret the client's request

[Virtualisatore]

Good Day!

We run a vSphere 4.0 installation consisting of:

- 2 x ESX 4.0

- 1 x vCenter 4.0 Server

For some reason we can't login using the vSphere Client directed at the vCenter IP-address any more (tested client version 4.0 and 5.0).

At the login we receive this Error:

The server 'IP-ADDRESS' could not interpret the client's request. (The remote server returned an error: (400) Bad Request.)

after clicking OK this appears:

vSphere Client could not establish a connection with server "IP-ADDRESS".

Details: The server 'IP-ADDRESS' could not interpret the client's request. (The remote server returned an error: (400) Bad Request.)

Does anyone know how this can be fixed?

We tried to reinstall the client, or use it from another workstation.

Is there any workaorund for it? At the moment we can only manage the cluster individually by connecting to each ESX' ip address, but there are no cluster/HA options. Neither the /ui weblogin does not offer any HA operations.

And yes, we have rebooted the server, restarted VMware Windows services, etc..., nothing helps.

Thanks and have a good day!

Hi,

So if you've verified the vCenter services are running ok be worth trying if you havent already to try and connect

with the vsphere client directly on the vcenter server and choosing localhost. Be worth verifying if you can access that way.

Also have you have you got web access enabled? does that work?

Thanks for your reply.

Connecting to localhost from vCenter produces exactly the same error.

By Webaccess you mean https://vCENTER/ui while using the local administrator credentials?

That works, but the Web GUI is very crippled.

We need to be able to use HA fuctionality again (vMotion etc..).
