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.
Thanks for this answer...had the same issue!Tony Witty
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)
