Unable to login to vSphere Web Client - [500] SSO error: Cannot connect to the VMware Component Manager

Hi,

I have been testing out the latest vSphere, and have ran in to an issue with the vCenter Server Appliance.

I was able to access it via its web address as well as by the vSphere Client but after I rebooted the host that it was running on I can no longer access it.

This is for both the web address and client.

When I go to the address i get the usual certificate warning but after that I get:

A server error occurred.

[500] SSO error: Cannot connect to the VMware Component Manager

The vCenter Server Appliance is a virtual instance on the host.

I am able to connect directly to the host and the VM is running, as I can open the console session to it.

All this occurred after I rebooted the host to complete the install of the Mega RAID CLI and LSI Provider .VIB's

Any ideas?

Thanks,

Marcus

I'm not sure if you still have this problem, but I had this issue in my lab.  I exported the logs and saw that vpxd wouldn't start because there was no certificate (I had been messing with them).  I ran /usr/lib/vmware-vmca/bin/certificate-manager and chose to restore old certs.  Restarted the services and I was able to get vpxd to start so I could log in.

HI I faced the same problem, after successful installation of windows vcenter server having sql database locally. I fixed this problem by simply re-creating ODBC connection, and after that restart vcenter configuration server service. Then wait for 10 mins.

Hope it will help...

are you using external PSC or embedded.

If its external then use this workaround

1. Shut down the vCenter Server services

2. Shut down the PSCs services
3. Started up PSC services then verified they were all running
4. Started up vCenter services then verified those services

If it is embedded then power of appliances then power on. ( do not restart)
