ESXi is up, attempt to login to vcenter and the web client appears to login but has a message displayed at top that it can’t connect to vcenter. Even using vsphere it just won’t login to vcenter.

Access the VMware vCenter Server Appliance from the web client and you get in fine.

Once in, in Summary you’ll see

Server:  STOPPED

Start it and it starts fine but still can’t login.


Go to Setup Wizard and Launch to re-setup the vcenter seems to fix it. Just use default config.
Before you start that you’ll want to stop the Server and Inventory Service. Also stop Log Browser and vsphere Auto Deploy. It could be just Server and Inventory Service that needs to be stopped. Anyway. If you don’t, the wizard eventually fails (as I found out) with the error:

Failed to execute ‘/usr/sbin/vpxd_servicecfg ‘service’ ‘start”:VC_CFG_RESULT=101(Error: vCenter Server failed to start.)
